No bitcoin hasn't be legalized in any country although more countries are showing positive signs to adopting blockchain technology (note I didn't say bitcoin) but in adopting bitcoin I don't think that will ever happen. About the price of bitcoin been stable, that was just due to the lack of activities occuring in bitcoin of recent making it less responsive to news. The pattern of growth was due to the bear market, potential investors weren't sure if to buy or not. But I guess that's all over now.
