@grizgal Rates varies on demand, I've seen rates for USD upto 0.2% per day and crypto rates around 0.03% per day. Ratesare paid in the currency you are lending. If you are lending BTC, then you get paid in BTC, if you are lending in USD then you get paid in USD etc.. There is no need to convert to any particular currency to lend. Lend in what ever currency available.
