Did you know there is more than one kind of Bitcoin? It's true. If you want to know more about what bitcoin to buy you can learn about it right here. In the beginning, there was only Bitcoin. It was the brainchild of a person calling themselves Satoshi Nakamoto, although whoever that was may have had help.
Today, the three Bitcoins that exist are Bitcoin, Bitcoin Cash, and Bitcoin SV. Bitcoin is still the most popular of the three, and it is also the most valuable crypto as measured by market capitalization. Most major investors buy Bitcoin, and it seems to be a bell weather in a market that can be wild at times.
Bitcoin Cash was a fork of the original Bitcoin blockchain, and it was designed to be faster. The original Bitcoin was designed to be more like a store of value, and Bitcoin Cash worked to be a faster way to settle transactions. Bitcoin Cash is still valuable, but not nearly as valuable as Bitcoin.
Bitcoin SV (Satoshi Vision) is a split from the Bitcoin Cash blockchain that occurred in 2018. It was designed to keep the transaction fees on the network low, which is thought to be more in-line with what Nakamoto had planned for Bitcoin.
