You have to be careful when it comes to staking. Any incentive should be looked at and considered when making an investment, but there are alt coins that use generous incentives as a way to lure unsuspecting investors in to take their money with pump and dump or other schemes. Just make sure you like the asset, not just the incentives.
Not just that, luring them into their own platform for which they hold their funds and the poor staker will have no means of getting their funds back.
I'd be very careful with them because all of those APYs could be interesting and attractive.
But we should lean on what's believable and what is the reality that it has got because in everything in there, there are risks that needs to be considered.
