The time of speculative trading will never end. In the stock market, all stocks also have a significant speculative price component. We can say that the market is not perfect, and market prices almost never correspond to the base price of an asset.
In crypto, most assets have only a speculative component. That is, in fundamentally, these assets are worth nothing.
Yes, the market is not perfect, today cryptocurrencies are almost entirely based on speculation, they are not controlled by any bank.
And you think that other markets are not speculation? If you want to buy cheaper and sell at a higher price, this is speculation. And by the way, the banks themselves are speculating. They take a deposit from people at a small percentage, and they give loans at a high percentage.
