Bitcoin SV (short for Bitcoin Satoshi Vision), as the name suggests, was created to make it the real Bitcoin, as envisioned by Satoshi Nakamoto, the creator of Bitcoin.
The previous year, during the month of November, Bitcoin Cash (BCH) hard forked into Bitcoin ABC (Adjustable Blocksize Cap) and Bitcoin SV. There are a few features provided by Bitcoin SV like: Size - Bitcoin SV has the biggest block size - a gigantic 128 MB Cost - The transaction costs of other coins like BTC or BCH is quite high. But BSV was made with the intent of having cheaper transaction costs making it affordable and fast at the same time. Network Development - Bitcoin and Bitcoin Cash had some discrepancies in them regarding many aspects including its network as well. And as Bitcoin SV was made to implement Satoshi's view, its network's more developed than that of Bitcoin Cash or even Bitcoin ABC. Bitcoin SV's Craig Wright claimed himself to be the real Satoshi Nakamoto (which is not true). He was also involved in other controversies like the famous hash war against Bitcoin ABC's Roger Ver, suing others in the crypto world or the recent one of him involved in the fake news that 'might've' caused BSV's sale to skyrocket by more than 90% in a day. This fake news, circulated on Chinese social media, revolves around Wright transferring 50K BTC to Binance from the biggest BTC wallet, and hence proving him to really be Satoshi Nakamoto. This is the key reason why Bitcoin SV is soaring so high.
