Noup, never. Bitcoin is still not a steady currency, but $ and is.
Earning your life on BTC doesn't mean you're holding it for it to go up and down. And FIAT isint really all that stable either. 15% deviancy in a year isint really what one should call "stable".
Bitcoin is not nearly as steady as USD or EUR. You may not think 15% is steady, but if you think that, then you must think BTC is absurdly unstable.
BTC is not steady as steady as FIAT yet in terms of price, or merchant acceptance. As in, merchants actually have accepted BTC, then chosen not to anymore.
All of this is okay though, I think BTC will prevail. Just a long road ahead.
