Bitcoin is the first cryptocurrency created in 2009 by a person or group of people under the name of Satoshi Nakamoto. Bitcoin was proposed as an alternative to the conventional banking system in the wake of the financial crisis of 2008. Unlike banks, the Bitcoin network is a decentralized anonymous peer-to-peer payment system designed to the way that it is almost impossible for a single entity to gain control over this network.
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.
