I realise that the simplest way to make a profit on crypto at the moment seems to be just buying and holding Bitcoin, but I'm curious if there are any coins or tokens designed specifically to generate ongoing passive income for holding them and if so, how they work?
Appreciate any replies,
There are some altcoins with POS algorithm which can generate passive income for you. It works on proof-of-stake basis. It rewards you if you hold some amount of that coins in your wallet. The rewards are automatic and you will keep receiving free coins based on your holding amount as long as the algorithm permits. However, the POS coins are not very successful in the trading market. At least I don't know about any POS coin which has a great value probably because you can receive free coins. (I may be wrong on that, so please correct me and let us know about valuable POS coins if you know any). So the best way to generate a robust passive income is to hold bitcoins for a longer term like 3-5 years. It will not increase the amount of bitcoins you hold over time, but it will increase in value for sure.
