Greetings @crypto.piotr
Every time a DeFi offers a high APY is synonymous of failure or very short life of the project, since the first investors do not think in the long term, but in being able to capitalize, monetize and get out of it , it is very difficult that a DeFi can stay like that. i think that if the developers would think in a long term DeFI they should not offer such exorbitant APY that only attract short term investor
