Well staking isn't a get rich quick scheme, but you can make some sort of "passive income" by staking the right coins. On the other hand you need a maybe hefty initial investment, as you have to buy some established POS coins with more value than 6 sat each
.
I know that we need a good investment to start.
In you opinion which coins are the best to stake?
Well, as I'm not staking nowadays my informations are probably outdated but PPC, HBN, CLAM could be a good choice, perhaps Cloak, DMD as well. XPY is still something what you can sell, but I wouldn't invest too much into that coin. I do not have any experience with iGotSpots's latest stuff but you might want to ask some users about that too.
