I almost do not believe in projects that provide APY up to thousands of percent, it really looks like a scam or it won't last more than a few months. this really brings too much risk, I would never staking such projects.
Should choose projects with a reasonable percentage and those that have been recognized as safe to invest and stake. Along with that, choosing a platform to stake is also extremely important, we should only stake reputable, leading platforms.
That is because they are 99% scams and 1% will fail, that is why. Any project that offers thousands of percent APY returns cannot sustain that and will either go down to a realistic level or they will be gone. Look at Pancakeswap, they provide something realistic for the good ones, but look at the small cap stuff there, they are offering high levels but their prices always keep on crashing lower and lower and can't be sustained and never stay high.
This is why if you see a project that offers anything high, you should stay away from it. Things like 20-30% is not really impossible in crypto, that could be done, and things that are 10% or under are usually decent.
There's no brainer if we do compare out bank interest to APY which been offered with staking with altcoins which you do say that most of them are scams and the rest do really fails. 5-10% APY is really realistic
but offering above those numbers are basically not really that suggestable for you to engage on and as been said or mentioned that its price would be crashing until you do end up on earning nothing or peanuts.
Its never been recommended to consider out staking as a good way of investing considering the duration and risk involved into it.
