On 1 August 2017, there was a split from normal Bitcoin. The Bitcoin Cash was born.
Bitcoin Cash results from an argument in the bitcoin scene, how Bitcoin is to be further developed. The problem is that only seven Bitcoin transactions can be performed per second. More can not be posted in the blockchain, the database. Because of the increasing popularity, many Bitcoin users had to wait for hours until their transaction was carried out.
Storage capacity: The biggest difference is in the block size with the new currency Bitcoin Cash. Instead of one megabyte as before with the Bitcoin, the storage capacity is now eight megabytes.
Transactions per second: With the increase of the storage capacity bitcoin cash up to 50 transactions per second are possible, with normal Bitcoin only 7 transactions / second.
