Why do you guys think Bitcoin will really become the "money of the future" and people will actually use it like one?
From what I see, I think it's possible that people in the future will still trade bitcoin or try to buy as much of it as possible to manipulate the market.
being the currency of the future does not mean bitcoin has to be a stable currency, bitcoin cannot be stable because of its price volatility and also bitcoin forever is decentralized. if indeed you want a stable crypto currency (similar to fiat) then just choose DAI, USDT etc.)
the thing that you must know is that manipulating the price of bitcoin is very difficult, you have to have it in large quantities whereas currently only a few people or groups have a lot of bitcoin, so that in the future even though people continue to trade bitcoin the price will continue to be volatile and difficult to manipulate.
