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.
I agree with you but last time cryptocurrency becames more stable. Only new altcoins can have very volatility price.
Of course, we can complain, but all this is just another stage of the emerging industry of cryptocurrency, speculation and volatility reduces stability.
