However if one already owns bitcoins, this problem that you have becomes non-existent.
I agrre the statement that bitcoins cannot replace fiat being an alternate as a global currency because as long that bitcoin would not legalized to the whole world,bitcoin would not considered as a traditional currency,because maybe some country would agree this implementation,while the others are not,so the decision is mutual,so for me its a long story happen before bitcoin would replace fiat as a world currency.
