If bitcoin cash takes over as the top cryptocoin in market capitalization, I reckon it would be bad not only for bitcoin but the whole community as well.
We know bitcoin cash is the altcoin, and it does not have the best developers working on it. I also reckon some miners will start mining BCC because it would be more profitable for them. What then should the basis be for calling either BTC or BCC as the real bitcoin?
Is it the developers, the price, or the hashrate?
When Bitcoin Cash have bigger marketcap and higher hashrate, it become the 1 True Bitcoin.
Core segwit version be left to die.
