Maybe , but the thing is , its too far for the bitcoin to stand out from all kind of crypto-currency which may give trouble for those who are not using bitcoi, it may have higher from compare to dollars but not in the sense that papar money will be extract from transactions daily and payment on a simple negotiation in the market, someone should finance a worldwide fast and free internet so most of the people can do transactions through it.
