BTC's unpredictable price is also a positive attribute that Bitcoiners like. you can make money out of this inflation. but BTC may not become stable due to the cycles, when the cycles probably are over like all 21M coins are already mined, I think there will be stability of price.
Yes, but that's the problem. When you say that we can make money out of it, it means that you treat it like an asset and not like money to pay for everyday stuff. You can treat it like both, but for most people there fluctuations will be a bad sign because you can not only earn some money out of it, but also lose them due to the dip.
That's the reason why Bitcoin will never become a stable currency. Even fiat currency can't be considered stable because the price of it still moves, and so is Bitcoin.
The fact that people see Bitcoin as an asset where they can make money from it makes Bitcoin excluded from it being a stable currency. Some see it as an asset, and some see it as a currency, and this kind of thinking towards Bitcoin is the reason why it will never be a stable currency. Fluctuations will be a bad sign? Volatility is a double-edged sword. It can give you profits, but at the same time it can also give you losses, and it all depends on the investor.
Bitcoin will never stabilize, as some of the investors see it as an asset like Gold, Silver, or the Stock Market as a whole. I guess it's a good thing that Bitcoin is a currency where we can use it to buy stuff, but at the same time, it can be an asset where people can make money off of it.
