BU is bitcoin.
It's BU vs Core, not BU vs BTC.
BU and Core both are both bitcoin right now, so it's unfair to call the one bitcoin and the other not.
In fact BU even has more hashrate, so if anything, BU is the real bitcoin right now.
BU vs Core is really bad drama in my life, that's give a lot of the impact for the market. This such BU coin will be the other shit coin if that will be got release in the future. totally crap BUllshit.
