Correct. You could also solve the "unit of account" and "store of value" problem by pegging your crypto-currency to the USD, 1:1 exchange. Then you get the advantage of the decentralized transport network and the stability of the dollar (or any other preferred real world currency).

It's tends to not be a popular opinion around here (there are probably a few with vested interests), but Bitcoin as a currency is fatally flawed. It's supply is structured so that Bitcoin perpetually increases in value, thereby perpetually slowing down the velocity of Bitcoin transactions.
