i don't think stability will ever be achieved by bitcoin because for one, bitcoin possesses a tremendously volatile characteristic and with that alone, stability is very much hard to achieve; that is if we are talking about its value. so long as there are people that buy and sells bitcoin and mines it at the same time, bitcoin will continuously become unstable and i think that is a good sign because for people who invests in it especially long tern investment, stability implies that there will be no profit gained.
