Bitcoin Cash is now insurance against not raising block size to 2MB in November as Segwit2x prescribes to do.
Forking to raise the block size to 2MB doesnt make sense now. Why do we have to go through all that risk for a 2MB block size? Theres an 8MB block size available in Bitcoin Cash, why dont the groups who want bigger blocks like Bitmain support that?
Because those with substantial hodlings in BTC don't want to risk a sudden transfer to a relatively new asset class.
