Stay away from projects with insanely high APY, 100,000% to 500,000% APY, you knew what I'm talking about, Titano, Safuu and others, invest but learn to back your initial investment first, all these defi projects are practising ponzinomic scheme. The latest is Safutinano, just know what you are doing.
I am actually avoiding this kind of high APY. I always wonder where they will get the amount to pay for the interest of their depositors. Besides, it was already proven that this kind of high interests is not sustainable. I also observed that the more people participate in the reward the lower the APY becomes.
