Within this scope, I feel that there are two biggest ways to generate passive income from cryptocurrencies, and I also use them and see other people using them.
the first is trading. although the risk is big, but I think we can control that risk by creating a safe zone when we trade, whether it's in the short term or long term. however, I do most of the long term trades. waiting for the right time always gives a very good profit.
The second is staking. the origin is very easy, it's because we don't need to do anything, and nowadays this method is very popular. however, we just need to keep the coins or tokens we have to earn interest from it. it's just that, from every passive income, there is a risk. well, I trade most of the time, and hold it.
