I don't get it. It will actually be bad for BOTH chains if indeed Bitcoin forks into two. Some people who are following the space could see this as a weakness and another reason not to start investing or accepting BTC as payments. Imagine if you were a merchant and you have to go thru and be involved in this sh*t, with all the debates and the drama. And worst of all the uncertainty of BTC's future.
Because one of them wants to allow Bitcoin to scale, the other doesn't. duh
It is not really as simple as that. The incompetence of the BU developers is also at play here and it will be a very important point to emphasize that they do not deserve to be in the position of the Core developers. I have nothing against BU and what its trying to acheive. But please find better developers.
