Hearing Aids : Key Players, SWOT Analysis, Key Indicators, Forecast and COVID 19 Impact Analysis 2030
COVID-19 Impact on Global Hearing Aids Market The emergence of the COVID-19 pandemic has changed the delivery of medical care across the world. The increased pressure due to the growing rate of hospitalization of COVID-19 patients had led to the re-profiling of many hospitals and departments for treating patients with COVID-19. Consequently, many elective surgeries were canceled or postponed worldwide to reserve or redirect the available limited capacities and resources (like hospital beds and patient care professionals) toward COVID-19 patient care. In particular, the provision of ENT-related surgeries and services has been disproportionally affected due to the reallocation of intensive care resources. According to the Centers for Disease Control and Prevention (CDC), ENT clinics and audiology centers pose a medium-to-high risk for COVID-19 infection, considering the proximity, test set-up, and length of appointments. The fact that a majority of people who require audiology services (aged over 65 years) are also the ones at the highest risk of COVID-19 related mortality and morbidity, underscores the importance of reassessing how hearing care is delivered. The outbreak of COVID-19 has led to an increase in the preference for remote monitoring. The crisis has ushered in a new era in the hearing healthcare space that requires a radical rethinking of service delivery in audiology. Low- and no-touch services are now necessary for audiology patients (who are typically at the highest risk for COVID-19 morbidity and mortality due to their advanced age). Also, hearing aid manufacturers have started focusing on including mobile audiometry and digital hearing care solutions for remote hearing aid device troubleshooting, counseling, fine-tuning, and tracking. Download PDF Brochure @ https://www.marketsandmarkets.com/pdfdownloadNew.asp?id=198630754 Globally, the rising incidence of hearing loss has made it extremely important to monitor and examine hearing functions. In children, untreated hearing loss negatively impacts language development, learning, and social engagement. Similarly, older adults with hearing loss often have difficulty following day-to-day conversations. For people entering their retirement years, untreated hearing loss has been linked to several physical and psychological issues, ranging from cognitive decline and depression to an increased risk of trips and falls. Emerging economies such as India, South Korea, Malaysia, Vietnam, Africa, and Middle Eastern countries such as Israel, Saudi Arabia, and the UAE offer significant growth opportunities to major market players. This can be attributed to their low regulatory barriers, improvements in healthcare infrastructure, growing patient population, and rising healthcare expenditure. The high cost of hearing aids, such as cochlear implants and bone-anchored systems, is a major factor restraining the market growth, particularly in price-sensitive regions such as the Asia Pacific, Latin America, and Africa. Healthcare providers, especially in developing countries such as Brazil and Mexico, have low financial resources to invest in sophisticated technologies. Moreover, the staff must be extensively trained for the efficient handling and maintenance of cochlear implants and bone-anchored systems. Extensive R&D activities are required to develop technologically advanced hearing aids. Currently, several countries are facing a shortage of skilled professionals who are capable of effectively performing ENT procedures, such as cochlear implantation. Underdeveloped countries and regions face this problem on a much wider scale. The dearth of skilled ENT surgeons in these countries is expected to limit the number of ENT procedures performed, including cochlear implantation, carried out per year despite the presence of a large target patient population base. The hearing aids market is segmented into sensorineural hearing loss and conductive hearing loss based on type of hearing loss. In 2020, the sensorineural hearing loss segment accounted for the largest share. Growing geriatric patient pool is driving the growth of this segment. The higher susceptibility of the elderly population to sensorineural hearing loss makes geriatrics a key segment of the overall patient pool. Request To Get Sample Pages @ https://www.marketsandmarkets.com/requestsampleNew.asp?id=198630754 The higher susceptibility to hearing loss makes adults a key segment of the overall patient pool. As a result, the growth of this population segment will ensure a continued and intensified demand for hearing aids. The global hearing aids market is segmented into five major regions—North America, Europe, the Asia Pacific, Latin America, and the Middle East & Africa. In 2020, Europe accounted for the largest share of the market. The European market’s growth can be attributed to the increasing life expectancy, rising geriatric population, and the subsequent increase in the prevalence of hearing loss. Some key players in the hearing aids market (2022-2026) Sonova Group (Switzerland) Demant A/S (Denmark) GN Store Nord A/S (Denmark) Cochlear Ltd. (Australia) RION Co., Ltd. (Japan)
How do Bitcoin scams work? And What will you do if you fall victim to Bitcoin Scams?
In Bitcoin scams, thieves take money from victims who actively invest in or use the new digital currency for transactions. How do Bitcoin scams work? Getting your lost money back from cryptocurrency fraudsters may be challenging because crypto assets aren't regulated or monitored by the government. Unfortunately, this is also the cause for the increasing number of scammers who fearlessly enter the cryptocurrency industry and prey on the unsuspecting ones. It is now up to the end-users to safeguard their assets. The following categories best describe cryptocurrency scams: Getting into someone's wallet: Bitcoin scams involve attempts to get into the target's digital wallet by acquiring their account login credentials. Additionally, scammers will attempt to access sensitive data, such as security codes, or they may even try to access actual hardware. Directly transfer or steal bitcoin: In these scams, fraudsters move cryptocurrency from the victim's wallet to their wallet by impersonating someone else, creating false business opportunities, or other nefarious means. What will you do if you fall victim to Bitcoin Scams? Ultimately, there are several ways to adopt when investigating a suspected Bitcoin Scam, depending on the circumstances. These options include investigating and pursuing the case through law enforcement, pursuing it through a private prosecution, or pursuing it through civil courts. Implementing compliance bitcoin tracing methods can augment any of these options. It's crucial to move promptly. But, first, consider reporting the purported fraud to Morgan Financial Recovery, which offers a thorough reporting process and more in-depth information. You can take further actions to help the investigation of your fraud allegations. Law enforcement authorities may or may not investigate the alleged fraud after receiving a report, depending on the factors that they’ll evaluate when determining whether to pursue the case. Therefore, it's crucial to think about the actions you can take to support any ensuing inquiry. Consider extra assistance by asking a specialized private business to investigate one of your alternatives in this area. For example, bitcoin scam recovery companies ought to carry out a compliance investigation that, if required, can be utilized to aid in civil or criminal private prosecutions and for additional actions under the law enforcement. The advantages of using specialized technologies are that it lets you follow fund transfers and collect evidence in a way that should also be admissible in any later cases with services provided by specialized businesses. It should theoretically be feasible to attempt to track all transactions and then provide evidence of the trails of any alleged fraudulent conduct because the blockchain (where all cryptocurrency transactions are kept) is a visual record. Conclusion: This article covered some of the problems dealt by victims of the Bitcoin Scam, and how Bitcoin scams work out there. The fact is that con artists frequently develop new fraudulent tactics. Hence, we take our users' account safety and protection very seriously. Before signing off, here’s a reminder that you should always report any suspicious account activity to Morgan Financial Recovery.
How to Send Form Data Using Axios Post Request In React
React is the leading programming language used by developers globally. More than 8,787 industry leaders were using React.js in 2020. Hence, multiple developers prefer to go for React and Javascript. Multiple encoding types can be used for non-file transfers. Form data: One of the encoding types allows the files to be incorporated into the required form data before being transferred to the server for processing. Some other encoding types used for the non-file transfers include text/ plain, application/x-www-form-urlencoded, etc. Moreover, Bosc Tech has a skilled developers who have developed various react application using React. Hire skilled React developers from Bosc Tech for your next project. While multipart or form-data allows the files to be included in the form data, text/ plain sends the data as plain text without encoding. It is used for debugging and not for production. The application/x-www-form-urlencoded encodes the data as query string — separating key — value pairs assigned with “ = “ and other symbols like “&.” All these encoding types can be added to the HTML using the “enctype” attribute in the following way: <form action=”/path/to/api” method=”post” enctype=”multipart/form-data”></form> These encoding types are used with HTML “<form>” tag. The default setting works well with the different cases; this attribute is often missing. Axios Axios is the promise-based HTTP client for Node.js and browsers. It makes XMLHttpRequests from the browser and HTTP requests from Node.js. Further, it supports the “Promise” API and can intercept responses, requests, etc. Axios can cancel requests, transform requests, and response data, automatically transform for JSON data, and offer client-side support to protect against “XSRF.” Axios is dependent on a native ES6 Promise implementation to be supported. It is easy for the users to polyfill if the system doesn’t support the ES6 Promises. Further, it is heavily inspired by the “$ http service” offered in “Angular JS.” More or less, Axios is an effective method to offer a single “$ htttp” like service for using it outside AngularJS. Browser support: Edge, IE, Opera, Safari, Mozilla Firefox, Google Chrome, etc. Also, check out our article on 4 ways to Set Input Field After Rendering in React. Common request methods: Some of the common request methods in Axios are: axios.patch(url[, data[, config]]) axios.put(url[, data[, config]]) axios.post(url[, data[, config]]) axios.options(url[, config]) axios.delete(url[, config]) axios.head(url[, config]) axios.get(url[, config]) axios.request(config) Common instance methods: Some of the available instance methods in Axios are: axios#getUri([config])v axios#patch(url[, data[, config]]) axios#put(url[, data[, config]]) axios#post(url[, data[, config]]) axios#options(url[, config]) axios#head(url[, config]) axios#request(config) axios#delete(url[, config]) axios#get(url[, config]) 1. Installing Axios: Axios is commonly used to send HTTP requests over the “fetch()” command. For different Node projects, it is easy to install Axios using “npm.” npm install axio or yard add axios The other way to install Axios is to include it in CDN directly or download the files to the system. The library in markup is included like: <script src=””https://cdnjs.cloudflare.com/ajax/libs/axios/0.27.2/axios.min.js”"></script> 2. Setting “enctype” with HTML and Axios: It is important to set the encoding type to send the multipart data or files through form data. It is easy to set the default global encoding type with Axios, which enforces all Axios requests in multipart/ form — data encoding type in the following way: axios.defaults.headers.post[‘Content-Type’] = ‘multipart/form-date’; The encoding type can be defined for separate individual requests by altering the “headers” in the following way: axios.post(“api/path”, formData, { headers: { “Content-type”: “multipart/form-date”, }, }); The third way to set the encoding type is to set the “enctype” in the “<form>” of a specific form. Axios adopts the following encoding type in the following way: <form action=”/api-endpoitn” methot=”POST”, enctype=”multipart/form-date”> 3. Axios and Express: Let us consider the case where a simple form with two inputs is created in Axios and Express. One is used for the user to submit their name, and the other one is used to select the profile image in the following way: Name : <input type=”text” name=”username” placeholder=”Enter Username”> <br> <br> Select a file : <input type=”file” name=”userDp” placeholder=”ChooseProfile Picture”> <br> <br> <button type=”submit”> Submit </button> If Axios is not used in the program, the default set of events unfolds. Pressing the “Submit” button will send a “POST” request to the “/update — profile” endpoint of our server. This default behaviour can be overridden by attaching an event listener to the button and preventing the unfolding of the default events. A simple example of attaching the event listener, preventing the default behaviour, and sending our form data using Axios is mentioned below. It is easy to customize the request before sending it out and altering the headers as all Axios requests are entailed synchronically. const form = document.querySelector(“form”); if (form) { form.addEventListener(“submit”, (e) => { e.preventDefault(); const formData = new FormData(form); axios .post(“/update-profile”, formData, { headers: { “Content-Type”: “multipart/form-data”, }, }) .then((res) => { console.log(res); }) .catch((err) => { console.log(err); }); }); The request is forwarded to the “http: / / localhost : 5000 / update — profile” endpoint with dedicated upload support files when the form is filled and the “Submit” button is clicked. It all comes down to the endpoint, which receives and processes the request. 4. Express Backend: The REST API is spun using Express.js for the backend support. Hence, developers can focus on development than on the different setups. This technique sets the server and handles requests. Express is expandable with middleware and works on minimalist coding. It becomes easy to expand the core functionality of Express by installing simple or complex middleware. Express can be installed using “npm.” The “express — fileupload” middleware can be used for simple file handling with Express. The simple technique for the same is: npm install express express-fileupload Let us start a server and define the endpoint that accepts the “POST” to “/update — profile.” const express = require(“express”); var fileupload = require(“express-fileupload”); const app = express(); app.use(fileupload()); app.use(express.static(“public”)); app.use(express.urlencoded({ extended: true })); app.post(“/update-profile”, (req, res) => { let username = req.body.username; let userPicture = req.files.userPicture; console.log(userPicture); res.send(` Your username is: ${username}<br> Uploaded image file name is ${userPicture.name} `); }); app.listen(3001, () => { console.log(“Server started on port 3001”); }); The “req” request passed through the request handler carries data sent by the form. The body contains all data from the different set fields like the “username.” All the files created are located in the “req” object under the “files” field. Further, it is easy to access the input “username” through “req . body . username.” The uploaded files can be accessed using “req . files . userPicture.” The following response is received in the browser console when the form is submitted with the HTML page: If information like encoding type, file name, and other information is required, it is easy to log the “req. files .userPicture” to the console. Wrapping Up: Hence, it is easy to understand the Axios post request to send form data. Axios is the leading asynchronous HTTP library that is used to send post requests carrying the file or multipart data. The REST API is used to handle the request. It accepts the incoming file and other form data using the “enctype” attribute. This attribute is set with Axios.
Auditing Smart Contracts
With DeFi smart contracts leading the cat of blockchain hacks in 2021, over $1.3 billion worth of cryptocurrencies have been lost to exploits, scams, and hacks. These massive losses can be attributed to unverified contracts, hasty forks, outright scams, and more. But according to the Certik DeFi security report, smart contract audit services the majority of operated projects are unaudited. In this article, we are going to look at what smart contracts are, how to protect them from bad market players. We will also look at some smart contract auditing companies and their areas of interest. Smart contract attacks Smart contracts are self-executing lines of code that obey instructions defined on the blockchain network. These contracts allow users to conduct trustless and transparent transactions on the blockchain without the need for a central authority or any legal system. Due to their utility, they have become the building blocks of complex decentralized applications, such as in DeFi and DExs, ICOs, voting protocols, and supply chain management. As clever as they may seem, they can lead to huge losses if any security flaws or bugs are found in the code. In general, the smart contract can perform the functions for which it was designed, but the presence of a flaw allows hackers to create codes that can interact with the smart contract to embezzle funds. - A good example is the recent Qubit Finance attack, where the hacker exploited its cross-chain bridge and stole 206,809 BNB tokens, or around $80 million. - Another historical example is the DAO hack in 2016, which resulted in a loss of $50 million. Known or Standard Smart Contract Vulnerabilities Race Conditions : When events do not occur in the expected order. In Smart Contracts, Race Conditions can occur when external contracts take control of the control flow. Reentrancy : In this case, smart contract audit a function is called repeatedly before the first invocation of the function is completed. One of the crucial solutions is to block concurrent calls in certain functions, especially when reviewing external calls. Cross-function Race Conditions : describes a similar attack of two functions sharing the same state, with the same solutions. Trade Order Dependency (TOD) / Forward Run: is another race condition that affects the order of transactions in a block. By manipulating the order of transactions, one user benefits at the expense of another. Oracle Manipulation : This type of attack is associated with smart contracts that rely on external data as input. If the input data is incorrect, it is still entered and executed automatically. Protocols relying on oracles that have been hacked, deprecated, or have malicious intent could have disastrous effects on any processes that rely on them. Attack by short address/parameter: This type of attack is associated with EVM. It occurs when the smart contract accepts incorrectly populated arguments. Thus, attackers can exploit poorly encoded clients by using specially crafted addresses to trick them into encoding arguments incorrectly before including them in transactions. Smart contract audit As with ordinary code auditing, the security of a smart contract is directly proportional to the robustness and quality of the deployed code. It involves an in-depth examination and analysis of the code of a smart contract. To do this, smart contract auditors check for common errors, known host platform errors, and simulate attacks on the code. Developers (usually external smart contract auditors) are then able to identify errors, potential bugs, or security vulnerabilities in the project’s smart contract. This service is of paramount importance in the blockchain industry, as deployed contracts cannot be changed or are irrevocable. Any defect will most likely render the contract dysfunctional or subject to security breaches which could lead to irrecoverable losses. These days, obtaining audit validation is an asset to gaining the trust of users. Steps of auditing smart contracts. 1. Review the consistency between code functionality and the project white paper. 2. Check standard vulnerabilities; 3. Symbolic Analysis 4. Automated Analysis by Automated Tools (Approach 1): Tools like Truffle and Populus are used for automated code testing. This approach takes a very short time and has more sophisticated penetration compared to manual code checking. Although it also has limits of false identification and missed vulnerability. 5. Manual code and code quality review (approach 2): In this case, the code is manually reviewed by experienced developers. Although automated checks are faster, manual checks account for false identifications and missed vulnerabilities. 6. Gas usage analysis; 7. Performance optimization 8. Report preparation. Smart Contract Audit Companies 1. CertiK : Certik was founded in 2018 and it is one of the favorites in the blockchain niche due to their transparency verification tools and proof engine which ensures top notch scalability and security. That is, their approach is primarily mathematical. The company claims to have detected over 31,000 vulnerabilities in smart contract code, verified 1,737 projects, and secured over $211 billion in digital assets. 2. Hacken: Another business offering audit services for blockchain systems like Ethereum, Tron, and EOS is Hacken. Although they don’t only offer blockchain solutions, bsc smart contract audit Hacken also offers security goods to IT businesses. 3.Quantestamp : Quantstamp is a blockchain security company with developers from major IT companies like Facebook, Google, and Apple. Quanstamp has a wide range of blockchain security tools and services including; a decentralized security network for auditing smart contracts. According to their claims, Quantstamp has protected over $200 billion in digital assets, and they have over 200 foundations and startups that have pledged their products. 4. ConsenSys: Founded in 2014, ConsenSys is a robust team of software developers, business experts, lawyers, security vendors. Its platform is based on the Ethereum ecosystem and aims to provide blockchain solutions such as product security and protection, financial infrastructure. The company has a smart contract security analysis product. ConsenSys Diligence; which provides crypto-economic analysis and automated smart contract analysis for the Ethereum chain. 5. Chain Security: provides products and services securing blockchain protocols and smart contracts. Chainsecurity is trusted by over 85 blockchains and has secured over $17 billion in digital assets. They have also partnered with PWC Switzerland to perform security reviews, build solutions that evaluate smart contracts, test and run performance metrics for smart contracts. 6. Verification of execution: Runtime verification uses the method based on runtime verification, which has increased standards compliance, wide coverage during runtime, to perform security audits on virtual machines.

Study of Smart Contracts: Concept and Evolution
What is a smart contract In 1996, Nick Szabo proposed the concept of smart contracts in the article “Smart Contracts: Building Blocks For Digital Markets”. The so-called “contract” is something like a clause or a contract, which records the conditions of occurrence and the corresponding executed clauses to support operations such as confirmation of rights; the so-called “intelligence” means automation and programmability. Therefore, Bridge Smart Contract Development Services is a programmable contract, and it can also be understood as a self-executing clause contract. In a computer, it is a self-executing program fragment. It is easier to save the contract, and it is run by a certain algorithm. Given the input, the corresponding output is obtained, which greatly guarantees the execution of the contract. Using the vending machine analogy can help us better understand the core features of smart contracts. When the user selects the goods to be purchased and completes the payment, the shipping logic will be triggered, and the user can get the desired goods, and this process does not require manual intervention, which saves the labor cost of selling goods. If you want to break this contract, you have to physically destroy the vending machine. Like POS card swiping machines, EDI (Electronic Data Interchange), etc., this analogy can also be used. Smart Contracts and Blockchain Smart contracts were proposed in the last century, while blockchain was born in 2009. By definition, smart contracts have little to do with blockchain. So why have smart contracts and blockchains been so closely related in the past 10 years? Because the blockchain can ensure that the smart contract cannot be tampered with, not only the contract content cannot be tampered with, but also the record of each call. The most basic premise for smart contracts to generate value is to have a strong underlying medium for storage, so that it cannot be physically damaged. However, the ontology of a smart contract is a piece of code, which is very easy to be tampered with, and how to provide a strong storage medium for it becomes a problem. This is exactly what the blockchain is good at solving — through the practice of Bitcoin, Cross chain bridge development it has been proved that the blockchain can make electronic records immutable in a distributed environment. At the same time, smart contracts are also feeding the blockchain, which greatly expands the business scenarios of the blockchain. After being combined with smart contracts, the blockchain no longer serves a single currency payment, and can be extended to all aspects of life. The rich application scenarios also pose new challenges to the capabilities of the blockchain. Blockchain 2.0: The Birth of Ethereum Bitcoin, born in 2009, uses technologies such as blockchain to ensure the ecology, creating the era of blockchain 1.0. Users can customize some things through script code, such as how to unlock a fund. These script codes are saved with the transaction, thus enjoying immutability and determinism. So from a certain perspective, these scripts can also be regarded as smart contracts. But they don’t work well. First, these script codes are not Turing-complete, which limits the functions that can be implemented; second, the development threshold is high, and the experience of writing complex logic will be poor, such as writing programs with JVM bytecode. In 2013, a young goddess Buterin proposed Ethereum, the core of which is to update and verify blockchain data through the state of the world. The biggest difference between Ethereum and Bitcoin is that complex logical operations can be performed through smart contracts. On Ethereum, the language of smart contracts is Solidity, Build a cross chain bridge which is a Turing-complete and relatively upper-level language, which greatly expands the capabilities of smart contracts and reduces the difficulty of writing smart contracts. Because of this, the birth of Ethereum also marks the beginning of the blockchain 2.0 era. Subsequently, smart contract technology has gradually penetrated into multiple business scenarios such as traceability, certificate storage, and supply chain. Status and Prospects of Smart Contracts From a programming perspective, a smart contract is a piece of code. Smart contracts have many differences and limitations compared to regular code, such as: single thread execution Code execution consumes resources and cannot exceed resource limits It is currently difficult to obtain off-chain data, such as weather information, game results, etc. Other restrictions like TPS These characteristics make the current smart contract ecology center on the governance of on-chain resources. Just like various ERC standards and governance schemes on Ethereum; there are various resource models on EOS, such as CPU, RAM, concurrent economic model, Rex, Bancor protocol, etc. Obviously, as far as the current ecology is concerned, the influence of smart contracts on the real world is limited. But things are always evolving. At present, there have been many researches devoted to breaking these limitations, typically Oracles (oracles, but often referred to as oracles), which allow smart contracts to interact with off-chain, which can greatly improve the use of smart contracts In the scene, it seems that a computer is connected to the Internet; for example, those attempts to break through the performance bottleneck of the chain itself, such as payment channels, cross-chain, plasma, and rollup, all break the shackles of security and performance from different angles. Undoubtedly, smart contracts will play an increasingly important role, and with the implementation of Ethereum 2.0 in the future, a new blockchain era may be opened. Smart Contract Technology Ethereum adopts Solidity as a smart contract language, Solidity is a high-level programming language created to implement smart contracts that can run on nodes that allow Ethereum programs. The language absorbs some features of C++ and JavaScript, such as it is a statically typed language, supports inheritance, libraries, etc. In addition to Solidity, the smart contract technology of each platform is also different. Next, we will introduce the technologies adopted by other platforms from the public chain and alliance chain. Smart contract operation analysis The function of this Solidity code is to access the _num field. This field is called a “state variable” and is persistently stored by the blockchain. Users can deploy this code on Ethereum or similar blockchains. Successful deployment means that the smart contract can no longer be modified. As long as the underlying blockchain is not destroyed, the contract will always exist. Anyone can call the contract interface through the “contract address”, and the information of each call will be recorded on the chain. Before explaining how this code works, let’s review how a traditional java program works. First, after the user compiles the java code, Build a token bridge it will be saved on the disk in the form of bytecode; then the user will call the program, which is managed and executed by the JVM; during the execution of the program, the call parameters may be recorded through the log, and the Disk for IO. Solidity’s implementation is similar. The difference is that the medium is changed from hard disk to blockchain, and from stand-alone to distributed. After the code is deployed, it is stored on each node in the form of bytecode. When a user requests to call a function, the call request will be included in the transaction and packaged into a block. Once the entire network reaches a consensus on the block, it means that the call is legal. Next, the EVM will call the bytecode, which is responsible for accessing the underlying state variables, just like traditional programming IO. Epilogue This article introduces the concept and historical evolution of smart contracts. Smart contract is a technology proposed in the last century, which has radiated new vitality under the wave of blockchain. On the contrary, the extensive application scenarios of smart contracts have greatly promoted the development of blockchain. To learn smart contracts, it is recommended to choose Solidity language, because it has the characteristics of some traditional languages. At the same time, the execution environment is completely based on blockchain, and the actual business development experience will be different from the previous programming experience. Readers can try to quickly build a blockchain environment based on FISCO BCOS, deploy a simplest contract, become familiar with the deployment and invocation methods, and then further enter the world of Solidity.

Tricks to Make Money with Copy Trading Platforms
Copy trading platforms are extremely popular due to the ease of use of the automatic system that copies the trades of experts. This success, however, is overshadowed by the numerous negative online comments. As a result, it is reasonable to ask, "Do you really earn money with these platforms?" How to Lose Money When Using the Copy Trader Platform I can't give you an exact answer, but I'm sure the majority of traders lose money. How do I know this? Since 2016, I've been promoting several brokers, and the statistics in my affiliate program control panel show that: ► Approximately 45% of new traders who open a real account stop trading within a week. ► Approximately 25% quit within a month. ► Approximately 10% quit within six months. ► Only 20% of traders are still investing. I have serious doubts that 20% will match the number of winning traders. Why? Still comparing affiliate program statistics, some traders who continue to deposit funds with some regularity. So, if a trader is profitable, I suppose it is pointless for him to continue depositing. Obviously, these are just hypotheses, because I can't see how much a trader earns or loses on the control panel. In this analysis, I'd like to play devil's advocate by assuming that only 10% of investors actually profit. But now I'm curious about how this 10% makes money! Look for mistakes made by copiers. I started a discussion with 100 people who complained in British and especially foreign forums to understand their flop. Aside from two respondents who spoke negatively about a popular broker, I discovered from this survey that: ► All dissatisfied traders have used the copy trading platforms at least once, but none have used the program for more than ten days. ► They all began with small amounts of money. more specifically (rounded amounts). ► 82 started with a capital of 200 €/$, 7 with 250 €/$, 4 with 300 €/$, 3 with 400 €/$, and 4 with 500 €/$. ► All 100 have never planned to diversify their investments. ► 84 traders entered the markets with no intention of determining the best times to trade, consulting an economic calendar, or gathering economic news. ► At most two "experts" have been copied by 76 traders. ► 61 traders have only invested in a single currency pair or financial asset. ► 48 traders have redeposited, paying a maximum of 50 to 200 euros. ► 27 traders exited the platform before even seeing the results of their trades. ► Nobody has ever talked to the trader they were impersonating. That's terrible! I am not surprised that 90% of those polled lose money. Given the fact that trading is not a secure investment, To make money with copy trading platforms, you must do the exact opposite of what these 100 investors did. User Manual Even if learning how to use it only takes 5 minutes. It is critical to study it in stages. ► Trading, simulating real-world markets. ► Experiment with issuing stop orders (authentic parachute). The traders you emulate are human beings who make errors. ► Market intervention (especially in real life). You can change orders and log out at any time with copy trading programs. ► Choose carefully who to imitate. Each trader you copy has a personal card that contains information about his trades and characteristics. The program displays the ranking of the best traders by asset category; however, this ranking is skewed due to the trader's popularity. In fact, the platform does highlight the best traders in the top positions, but they are also the ones who interact the most with the community. The first traders you'll come across are those who publish multiple posts and frequently participate in social trading discussions. Your objective is to find at least five traders, each specializing in a different currency pair or financial asset and having a different risk appetite. Each trader's investment capital must also be diverse. While it is incorrect to distribute the same amount to each trader you copy, An Investment Diversification Example ► Invest 100 euros in Trader 1, which specializes in the EUR/USD exchange and operates with 1:100 leverage at low risk, with gains ranging from 10 to 20%. ► Invest 50 euros in Trader 2, a Litecoin specialist, with a leverage of 1:200 and a high risk. ► Trader 3, gold specialist, low leverage, high payout ratio, 80 euros invested ► A Trader 4 index specialist receives a 70-euro investment. ► Invest 95 euros in Alibaba shares with Trader 5, a specialist. (*) You can balance profit and loss by planning your strategy from the demo by selecting five traders with different characteristics. Plus, even more importantly, no more than 10% was invested in any single trade. You must choose unwilling traders to increase your profits. ► To the overtrade. ► Scalping. ► High leverage. ► Deadly Sins One flaw with these platforms is that traders earn a commission for each trader who copies them, allowing them to do frenzied scalping. If the trader you are copying makes a string of bad trades, this will have a negative impact on your investment. Furthermore, if you started with a small deposit, this trade will quickly deplete your account. This type of trading is very popular, so if you want to make money, you must have an emergency fund on hand. The second and most important trick to making money with copt trading is to have enough capital to invest. Again, based on the statistics generated by the affiliate program's control panel, the traders who continue to operate have the most capital. This supports the theory that the greater the capital invested, the greater the likelihood of profit. In fact, the winning traders account for 10% of the pie. They all deposited more than $1,000. How much money should be invested and why? The minimum recommended trading capital for any platform is $1,000. However, these programs are insufficient. Why? The main issue for those who invest little money in this program is that they risk being forced out of the market right away. Because you understand this, simply select a single trader who scalps and trades with high leverage, and you can rest assured that you will receive a margin call alert from the broker in less time than you say. With low capital, your operations are limited to those that require less than the entire amount. Gains and losses are always proportional, but the real issue is that your trading is restricted. To protect your money, you cannot afford to invest more than 10% of your capital in a single trade. You have the following advantages by depositing 1200 euros (minimum recommended capital): If you have 1000 euros to invest (max 10% for each trade) and 200 euros as an emergency fund in case your traders make poor decisions.

METAVERSE – THE WONDERS OF THE ONLINE PHENOMENA
Think of a virtual world in which people live, work, shop, and interact with others -- all from the comfort of their own spaces in the physical world. This is known as the metaverse. Metaverse is a new technology, an improved version of an augmented reality that enables several people to share a collaborative, and immersive virtual space. The recent announcement by Facebook, now Meta, (NASDAQ: META) was created for a virtual universe that integrates each of its services. Various companies like Disney, Qualcomm, Nike, and Microsoft have shown immense interest in it. The metaverse market supposedly is projected to grow at 45.2% CAGR from 2024 to 2030, according to the latest Market Research Future report. DIFFERENT APPLICATIONS Owing to its appealing features and multiple benefits, metaverse has a wide range of applications such as, Healthcare- Considering the arrival of the latest 5G technology, telemedicine may attain new horizons. Using AR in the metaverse, healthcare can supplement maximum people’s requirements across the globe. For example, during an eye exam, doctors can use tools and devices from the metaverse to facilitate the diagnosis. Through this technology, ophthalmologists can capture the patient’s eyes through a three-dimensional view and also make use of sensors for collecting vital signs. Along with pre-operative pictures from 3D scans, MRI, and CT, AR headsets are utilized for viewing crucial real-time patient data like respiration rate, blood pressure, body temperature, and heart rate. Besides, physicians and nurses, AR can also be used by everyone for vein identification. Manufacturing- With the use of virtual reality, there are less chances of accidents taking place. A manufacturer will not be required to spend time or money educating new employees as this will be looked after by VR training. This technology also helps to create better products as every element can be examined through a VR goggle. Manufacturers can also create flooring through virtual reality. Military Applications- The military application of VR and AR have faced a considerable breakthrough. TAR (tactical augmented reality) is a technology that appears akin to NVG (night-vision goggles), but with high functionality. This may display the precise location of a soldier along with the position of hostile forces and ally. A synthetic training environment again is an AR system that has been designed for offering a realistic training experience via putting them in psychologically and physically demanding combat settings. Education- Through a VR headset, students are highly motivated to learn. With the help of this technology, teachers can develop a highly effective classroom environment. This also allows incorporating of any language in the software thus solving the issue of language barrier. Investment- Metaverse can fundamentally change the standard through which we socialize with others. The metaverse is the next big investment theme and the stock sectors are already benefitting from it. Metaverse - a virtual world for immersive experiences where people across the world can meet, play, watch, and trade - has gained traction this year after major companies. ACTUAL PERKS OF METAVERSE Metaverse will offer people with novel capabilities and new opportunities which they have not yet known. Affordability of Various Products and Experiences- Metaverse will boost up the affordability of different products and experiences radically thus giving the common people access to luxuries. Metaverse will allow humanity to travel the world virtually with superior quality interaction with families in distant places, and more. Also, most of the jobs which were earlier accessible only locally will now be accessible globally or nationally as remote work will be far better than it presently is over Slack or Zoom. This novel wave of information ultimately will develop huge new job markets. Development of New Possibilities- Metaverse will launch new possibilities which currently do not exist. Within a span of a few years through rapid VR development, people will have access to new possibilities that will offer much more than entertainment value. Sustainability- The metaverse will prove to be an immense boon for sustainability. By attending social gatherings, schools, and workplaces virtually instead of physically, people will indeed save precious resources. In short, the metaverse is the merge of the physical and virtual space. This possesses the potential of overcoming the limits that people experience in real life. This technology is surely here to stay for good! Source: metaverse market
