Bitcoin Cash: this alternative is not that far removed from Bitcoin itself. When Bitcoins market value soared last year, everyone wanted in and started investing. This created a backlog of transactions because miners couldnt add enough blocks in time. Bitcoin Cash split off from the original back in August 2017 to solve the problem. Known as a Hard Fork, Bitcoin Cash works the same, except its blocks were increased from 1mb to 2mb of data to help speed up transactions and keep fees down. Since Bitcoin dipped, however, the price of Bitcoin Cash has gone the same way.
