I do my DCA daily on BlockFi where you get 4.5% yield on Link. I also have some on Nexo that gets a 6% yield. In the DeFi realm, I have a bit of Link lent out on Unfederal Reserve's platform, but the ERSDL rewards end in 4 days so it's probably not worth it right now. You can always check Defirate.com to explore some of the biggest platforms and the yields that they are offering.
