So on copycat coins why would they have value if there a 100% duplicate or clone of a coin. What would make somebody like yourself by a coin that's 100% clone
Well, they aren't really 100% copies. Take litecoin as an example. It has block size, mining and halving but the amount of litecoins is 84 million, whereas there is only 21 million of bitcoin possible. But yeah, these are minor changes.
Ethereum and Byteball are among coins really different from bitcoin and its clones. Ethereum is a platform with a variety of possibilities which can still be created.
Byteball doesn't even have a mining system and yet the amount is increasing with time due to the code. And both offer smart contracts which are hard to be performed with btc.
