How long have you been interacting with Defi and other platforms which generate yield for their liquidity providers?
It should be previous to you and anyone with enough experience on crypto finances that those returns you see in Defi and also in Cefi come with a risk, otherwise they would not be significantly higher than returns from banks and other traditional institutions.

I have myself witnessed at least two major hack against Defi platforms, one of them was Pickle Finance, which got it's liquidity pools emptied by a cyber criminal. I would not call Defi yields one hundred percent reliable or free of risk, in the same manner we have seen people getting their lost gone from centralized yielding, that was the case of nexo and other website I don't recall at this moment.

Do your own research before trusting your Stablecoins and floating assets to Defi or Cefi.
