This can't be right. 7% APR (annualised rate) is way too low. At the current rates you should be getting something in the range of 30% APR (27.8% net of fees), so perhaps you meant 7%/month?
Ops.. You are totally right. I actually confunded this info with something else in my notes. Sorry about that!
I was actually getting something close to 23-26% per year because of the floating rates.
Still a pretty good rate if you store your coins in an exchange anyway. And better than doing faucets all day for some cents.
Anyone knows how the bot chooses rates? Does it just match the lowest loan offers, or is it more advanced, (i.e. measuring depth, or just ignoring dust-amount loan offers)?
I don't know exactly how the bot operates to get the best rates, but you can always set up a minimum and maximum rate. I just used the default config because I'm too lazy.
