Because the Bitcoin Unlimited is a fork from the bitcoin itself. It's mean if that will disrupt the crypto community.
We do not need the Bitcoin Unlimited coin. It will be worthless in the future.
Well, if I were in charge of Unlimited I would start it off as a fresh alt and forget forking completely. Their blockchain could start in a similar way to Clams, take an image of every BTC balance and start from there.
They'd have plenty of mining grunt to get up and running and no shortage of awareness. If people like what they see then they can buy in with their BTC.
Exchanges have already stated they'll list in the case of a contentious fork, no doubt they'll be delighted to list something that isn't the child of strife. If it really is superior to its daddy then the market will naturally migrate with no risks to anyone or anything.
That would have been a better idea as instead of trying to replace bitcoin or forking it,build a better crypto and let people decide which one they want to use.
Forking has started unnecessary confusion and division among community and is not good for either btc or BU.
