I don't understand why many people are hoping Bitcoin would be a central currency. I don't think it was ever designed to be one and I don't think it would ever be. Except it becomes centralized. meaning it can be influenced by a third party (the government).
The last thing you want is a Bitcoin influenced by the government

The fact that Bitcoin is not serving as a currency is not an imperfection rather its a peculiarity. No one can change this fact.
