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.
