I think if bitcoin rose quite steadily and slowly people wouldn't look at the best cryptocurrency with an "evil eye". Going forward, do you think a slow steady rise, rather than a speedy erratic rise is good for bitcoin to get "accepted" all over the world? The sudden rise seems to scare people and governments.
Yes, a more stable and slow bitcoin in terms of price was a better option than the current bitcoin with its high volatility. However, unfortunately, so far we can not change anything in this matter. Decentralized bitcoin will always have high volatility and this will be the main obstacle to its use as the main currency in any state.
Of course, everything changes, the crypto currency is gradually improving. Perhaps, in the future there will be opportunities to eliminate this drawback of bitcoin.
