of course, cryptocurrencies have fundamental values, so that makes cryptocurrencies can be popular and in demand by investors to be used as a long-term investment, but I don't agree if you say that cryptocurrencies have a low risk with high return, because in my opinion investing in cryptocurrencies has a big risk, although it is true if the return is high.
What needs to be understood is that every investment is always risky, the matter of high or low depends on the conditions and how much capital we use for investment, because large returns will only occur if market conditions can be very profitable, and vice versa.
