Bitcoin has never lost its high price volatility. A decentralized cryptocurrency will always have it. If the price of bitcoin for a relatively long time as a whole stands still, this is most likely an exception based on the counteraction of several opposite factors.

Thats when bitcoin is going to become a real digital gold
