The crypto bull market is predicted to be coming and probably most tokens or coins will touch their new all-time high.
The best way to generate passive income in crypto is to buy different coins in small amounts and hold them for a long. There are high chances that you will generate passive income by just holding most of the coins.
That is still passive income when the value has grown over time but that is not the type of passive income many does want.
But in fairness of holding, you will never get wrong with it but you need to choose wisely on what you want to hold. Because if they are just bunch of memecoins, forget about it because they are not for long term holding.
