I've been staking in some of these projects, honestly the APY is just like normal APY, most of the people that uses restaking protocol only want the airdrop, not the real APR that they offered, I think this kind of project suits you best if you just have some ETH lying around, earning on the side by just staking it. right now I think they also proposes 4th season of airdrop, probably just gonna reuse previous eligibility criteria.
Exactly, it's a way to get more rewards and the potential airdrops that will be released through these restaking protocols that are partnering up with them. If someone who's into airdrops does this, it's fair for them to get that much tokens to sell and have of a great value afterwards because it looks like a way to invest but they get their money back and with some airdrops on the side. There's also risk on it but those that knew what they are up to and what they're doing, this is easy money still aside from the APY that they get.
