I just wonder how bitcoin really works on local exchange around the world because if you will going to need a real money and you have bitcoin definitely you can sell your bitcoin and exchange it with real money in your local to be used. Well if all people around the world would exchange their bitcoin holdings is it possible because bitcoin is being back up by real money?
That is what happening now while bitcoin is in a stage of public analizing towards negotiation for final acoption for every people. You are definitely true local exchanger now is a back up of bitcoin to fiat money.
