do not mean trade bitcoin to buy/sell i mean using it as a way of payment say you wanted to send money to someone abroad for family far away
this is not part of the context too,if the internet goes down because you will have no access in your wallets then.so the thing is no sending to anyone from anywhere and this is a very bad situation if we faced this in future.
Well if this happens all this crypto coins will have no value,1/4 of the worlds economy will drop since this percentage represents the totality of crypto to the economy..but i hope this would never happen or if does hope i did manage to exchanged all my funds into fiats
