Bitcoin Cash is the most popular Bitcoin hard fork proposed by Roger Ver in 2017 as a solution to the problem of slow transactions in the Bitcoin network. The idea was to create a version of Bitcoin that would be better for payments, while original Bitcoin is considered more as a store of value. Bitcoin Cash has a bigger block size than Bitcoin so the transactions of this currency are faster and cheaper. On the other side, it requires more resources to run the full node of Bitcoin Cash which makes it more vulnerable to centralization.
Bitcoin Cash quickly attracted a huge following and became a prominent part of the cryptocurrency market. BCH is available on many exchanges and is supported by numerous crypto services. Since the launch of the project, it has never left the top 10.
Bitcoin SV is a Bitcoin Cash hard fork that took place in 2018 as an alternative to Bitcoin Cash ABC. One of the core developers of Bitcoin SV Craig Wright believes that Bitcoin SV is much closer to the initial idea of Bitcoin than Bitcoin Cash ABC. The dev team of Bitcoin SV is focused on fast transactions. Their goal is creating use case opportunities for Bitcoin.
Bitcoin SV survived a series of delistings from several notable cryptocurrency exchanges and managed to keep its high position on the market. Bitcoin SV is one of the top 10 cryptocurrencies by market capitalization and its daily trade volume is similar to its rival Bitcoin Cash ABC.
