What do you think this means?
It only means that does attacking bitcoin will never make any different but face defeat and failure. I dont think this is a battle between David and golliath, because bitcoin never been doing a move to destroyed bitcoin cash because it was already been since it was made. And Im sure that a shitcoin(bitcoin cash) doesnt deserve to be called a worthy opponent to the pedestal that bitcoin has been all the time.
And what actually triggered it?
The bitcoin supporters is just playing bitcoin cash for self-interest and that after being in that situation seems they understand that the only thing they can do is surrender.
