There are other sources of yield, such as Gemini Earn (6.5%), which lend to larger trading firms. Those feel riskier since they're more exposed to systemic collapse in crypto and lock up your dollars with a long withdraw delay.
Then there are the ponzi yields (10-40%), like the recently collapsed UST and the soon-to-collapse USDD and USDN. I think it's obvious why those are a bad idea.
