This question cannot be answered unequivocally. Bitcoin is widely used now as a speculative financial asset and has very high price volatility. By this, it attracts most of the participants in this market, since it provides an opportunity to receive high profits, which are much higher than in other markets. However, the use of bitcoin mainly as a speculative asset does not allow it to be widely used as a means of payment and, thus, it does not fully fulfill its purpose.
The price volatility of bitcoin, like that of all cryptocurrencies, is both a boon and a downside. But this is inherent in the nature of decentralized cryptocurrency and it is unlikely that anything can be changed here.
