Of course, cryptocurrencies will not go anywhere, but their value is still in question.
If cryptocurrency remain in our lives, then their value will change from time to time. It would be nice if the cryptocurrency will be used in everyday life. In this case, the volatility of the assets used will decrease, so prices will be stable and increasing.
At least, then there will be no such rapid fall in prices of cryptocurrency on the market. And we will not incur large interest losses.
