I suspect the politics and the movement of bitcoin towards bitcoin cash is a short term storm in a teacup.
Most likely Bitmain just wanted insane profits for R&D to compete with the new Japanese mining hardware we keep hearing about.
I might be completely wrong, but if you look at the size of the hash power shift and the speed at which it took place, it does seem a bit suspicious.
The truth is that no matter how much we all think we are experts in crypto markets, none of us actually are. Most of the giants had no clue on what the heck was going on with bitcoin cash the other day..
We can all just dip our fingers in this business and pray that we all come out as winners in the end..
