This is one of the sources that I've loved to have before but not anymore today. While those that have you mentioned are the most popular in the masternodes scene.
The return of having those will take time and I have seen how expensive most of them before. Instead of getting into masternodes, just avail a coin that has a POS feature and have it staked.
Although they are likely similar but it's easier to stake because you don't need to go through the required amount in setting up a MN.
Thank you for your response. Any specific staking project that you are looking into and would like to recommend?
The most known is Ethereum although the need is around 32 ETH, you can join pools that won't require you that much and you can stake any amount but I have no list of that as I don't stake ETH. Btw, for other altcoins that you can stake. You can check resources like this link[1] below for your own reference.
