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,.
Even if every face of the earth is full of Bitcoin investors, volatility will always take place, and there is no amount of support and news can make Bitcoin more stable, the price action of Bitcoin is not about the adoption, if not, bitcoin wouldn't have grow from 100s to 1000s in the past, and that time the adoption rate was at it's lowest.
You need to understand the market situations and long-term chart play, it's inevitable, and that's just perfect for Bitcoin, if you are seeing the disadvantages of Bitcoin as complete disadvantages then you understand nothing about it, every disappointment is a blessing like my people use to say, and every bitcoin disadvantages has its advantages. You are the one that has limited understanding.
