Can you explain me more detailed how can I get additional profit from COMP tokens with loans, where on Compound can I get loan in DAI tokens, what I need for it and what will be an interest rate per month? When I’ll exchange loaned DAI tokens on COMP will I for sure get the main 3.2% and an additional ~ 6% interest on it in COMP tokens if I’ll exchange some COMP tokens on DAI every month to pay per cents for my loan?
