The volatility of bitcoin won't end anytime, I think we have to give more time for more people to appreciate bitcoin and use it in daily business transactions. At the moment, I believe some form of regulation can help make things pretty much more stable than we have at the moment otherwise we shall experience more issues with volatility. The high price volatility of Bitcoin and other decentralized cryptocurrencies will never evaporate. On the perverse, if the expense of cryptocurrency will improve, the volatility will only boost, as the expense spectrum will develop.
As long as the price of cryptocurrency will depend on supply and demand, the high price volatility of cryptocurrency will remain. Still think the ETF funds can solve this problem, or at least will lessen the volatility of Bitcoin. The more control of the market, the less volatility it will be, now we still don't have any rule or laws to govern this market,.
Is it possible for bitcoin prices to go higher if you want to end bitcoin volatility? I don't think that because Bitcoin is the most volatile it has enough value globally. If bitcoin keeps a normal price instead of being volatile then no one will feel motivated to invest in bitcoins resulting in a withdrawal of investment from bitcoin and eventually nothing but loss of value. Investors are interested in Bitcoin because of its volatility. Bitcoin is decentralized so there is no chance for anyone to centralize it. So it is not possible to remove it from the volatile state. Many of us in crypto certainly want it to be more highly volatile but Bitcoin can be a big problem for risk averse people.
