You have no clue.
Bitcoin is very very close to a collapse. As we saw the other day, when half the miners leave segwit1x (btc), bitcoin comes close to a halt. We saw $100 transaction fees.
If there will be a fork (segwit2x) tomorrow, both segwit1x and segwit2x will have too little mining power and could collapse.
