Volatility is not yet a thing of the past, mate. Price might not be fluctuating the way it used to in the past, but that does not make Bitcoin not volatile again. As long as price still experiences up-and-down movement and it's not stable in one place, then we shouldn't be talking about Bitcoin not being volatile. Only stable coins are not volatile, Bitcoin still can't be completely predicted can only make assumptions and speculations, but you can't predict its next move.
Volatility is needed to attract traders, If there is no volatility in the market, it will be dead. Remember being stable and having volatility can occur at the same time like saying Bitcoin is trading in a stable range of x - y where x - y is the volatility of Bitcoin. With that, volatility will never cease to exist unless Bitcoin is declared to have a fixed pricing value. Volatility will never be a thing of the past, especially if we talk about Bitcoin market.

Expect BTC to rise even further in price as a result of increased adoption by the Russians. Slowly but surely, the world is recognizing Bitcoin as the next "Digital Gold". I'd say Gold's "death" is certain. Possibly even Fiat, too. We'll see what happens in the long run.
Fiat currency will never face "death" as long as the government that issues it exists. About gold, it has a real life usage, so being certain of gold "death" is somehow delusional IMHO. Bitcoin may beat gold but it will not result to "death" of gold.
