In our field if you can make long term predictions then you wouldn't call it volatile really, because you can predict what it is going to do exactly from a couple to a year up front sometimes even years up front. It only looks volatile to people who aren't sure what they are doing. (Yes technically by literal definition it is and has been but who cares about technicalities). You could entirely very safely predict that when regulations dog whistles would go through BTC will go into chaos while ETH would draw power from it just because why they are both used. (BTC would only stand if they make it something more).

Bitcoin’s total supply is set to reach its limit around the year 2140, which is still far into the future. Until then, people can continue dollar-cost averaging (DCA) into BTC, especially given the likelihood that its value could increase over time as the remaining supply decreases. At present, only about 1.1 million bitcoins are yet to be mined, while roughly 19.9 million have already entered circulation. This leaves a window of opportunity for accumulation.    cat sounds meaning
Once all bitcoins have been mined, miners will no longer earn new coins as rewards. Instead, they will rely solely on transaction fees. Whether those fees become high will depend on how much demand there is for block space at that time. If Bitcoin continues to see heavy usage, fees could rise significantly.
As for price behavior, it’s uncertain whether future market cycles will resemble today’s bullish and bearish swings. However, trading activity is unlikely to disappear. As long as people are willing to buy and sell, daily trading—including short-term speculation—will probably remain part of the Bitcoin ecosystem, even after the mining phase ends.
