Paraphrasing Torvalds, talk is cheap, show us the coin

Really, how long are they going to be planning to have their own digital coin? After all, I've been reading and hearing about such plans for well over a year already, but they are still planning and planning. I'm afraid the sad truth is that no government is ever going to release such a coin. If it would be decentralized (read, allowed to be mined by anyone), why would they ever risk to create a competitor (basically, another Bitcoin) to the currency they already have and fully control? Otherwise (if it will be centralized), how will be different from a digital non-cash version of the currency they happen to issue? In short, stop repeating bullshit
