1) Minimum rates - you can't set this with FRR. You claim people are happy to take what they can, and to some extent that's true, but part of this is because they CAN'T choose the minimum they'll take with FRR... This option alone would have a HUGE effect on rates (...)
I like that idea.
Arguably a good improvement with absolutely no downside for anyone.
Super-easy to implement, just add a new box "minimum acceptable rate" or something similar, can even be checked client-side with simple javascript code. Allow "0" for the lenders which will take anything, according to mjr. But
provide no default value and require the box to be filled, so that whatever they enter is a conscious decision.
Only re-offer their BTC or USD if the FRR > their minimum rate. Sit on the sidelines if not, and maybe check once an hour if the FRR raised to an acceptable level and re-offer then.
Exactly, if you have a default rate, you just move the wall to whatever that default rate is.
