I think we can yeah,meaning keep using fiat,but with bitcoin is a much more happier living i would say,
second,i don't think they can ban btc,it can still be used in p2p,and people will always find a way
Yes, there are still many paths to take if a ban is imminent and those using BTC and fiat will remain the same as they are now although there is little influence that must be felt by people in the market.
