I'm relatively new to this so coming up against the same problems stated in the above posts. The FRR delta looked like it would be a good way to go but all it does is create an offer at the offset and then it becomes a static rate and you can't use FRR delta on the auto renew. Where as if you can get lent out at FRR it's a dynamic rate both while it's lent out and for auto renew. So I'm still looking for the best way to do this but so far FRR for 30 days has been most rewarding.

Thanks for that. Obviously, they're not hard to find with google but being able to trust them is a whole different issue. I'll give coinlend a go when I get my funds back from the 30 loan it's out on at the moment.
