I think, just for my own opininon, bitcoin's price will never be stable because for the reason that we all know, bitcoin is a currency type generated and operated online which make it a cryptocurrency and I believe that the ups and downs within cryptocurrencies are just their normal feature but more likely, this type of currency is always experiencing large changes compared to natural currencies because it can be easily accessed and this is more likely one of the contributing factor why cryptocurrencies like bitcoin cannot be stable for a known reason.
