I am not surprised most people are not sure what the outcome of the fork would be, so it seems holding the two chain would obviously be the best to do after the fork. Even Cobra, the co-owner of bitcoin.org and bitcointalk forum hope it does not end up being the last days of bitcoin and begs for a fork with a new POW algorithm in case the unthinkable happens. Phew! Just tired!! No wonder bitcoin cash has been pulling some weight in value in the past few days.

I think it's not very safe try to sell BTC ou B2X just after the fork without knowing what could happen due to the lack of replay protection.
