Forking the Bitcoin network is a tried and tested attempt to create a coin to rival
Bitcoin which has proven to be futile.
I don't think anybody who created any of these forkcoins ever did it to actually rival bitcoin even if they advertised it as such (like bcash guys). They are like Chinese rip off products, they aren't making those to rival the original brand and to gain superiority in the market. They are doing it to make some money from anybody who is foolish enough to buy their rip off.
