When bitcoin stops being volatile, it will practically turn into stabelcoin. but then there will be a question of whether people will stay interested in it. After all, volatility allows you to earn, volatility attracts attention. So the lack of volatility is bad for bitcoin, but probably good for altcoins.
Volatility is the big attraction, particularly the large scale fluctuation increase the risk of winning big as well as losing. People fear about the volatility for some reason, but it is the feature that supports making good money. As mentioned the lack of volatility will surely be unliked by the common people who make something out of the market fluctuation.
In other views, volatility is a charm that is quite attractive to trading bitcoin, the average trader sees the perfect bitcoin side of its volatility to take advantage.
And indeed basically stopping bitcoin volatility is very unlikely because of supply and demand, which makes volatility itself, and that with an open market and no one can control it.
It seems that bitcoin fluctuations will always be high because of the large number of speculators, many people think that bitcoin fluctuations are controlled by several people, but if we look at the facts of transactions, we will say that everything happens because of market conditions or real transactions, a market cap of more than $ 520 billion, of course, requires large funds to make bitcoin price controllable.
Even if a person has a 90% owner of the total bitcoin circulating, more or less fluctuations will exist even though it is relatively small, so in my opinion it is impossible to eliminate price fluctuations.
