All these altcoins and platforms that offer very high APY's are not sustainable and will either lower them dramatically or just become a scam . I prefer a "lower" APY like 50 or 60% but that you know is sustainable in the long term.
Good projects only give realistic APY but if any other coin gives high APY then you have to be careful because it only attracts interest from highest APY staking influence, so I think coins from gambling don't offer high APY. The most important advice is never to be attracted to high APY because basically it is not a stable coin and tends to decrease in price so there is no profit impact from staking.
