Thanks for the reply, yeah I was looking for more defi strategies rather than exchanges/saving accounts.
You may consider the suggestion of logfiles about defi's. There's no other suggestion too except mk4 about what you're looking for.
Anyway, most of the dex that I've looked into its earn feature, there's no bitcoin yielding but I know that there could be a few of them since there goes the wrapped bitcoin that they probably have been supporting.
