In order to get 1000 USDC as a loan using BTC as collateral at 150% overcollaterization rate for 45 days at 10000 BTC/USD exchange rate, I need to place 0.15 BTC ($ 1500 worth) as coverage for my loan. The loan creation fee is 0,5% of the collateral and must be paid in ILK, in this example it means $7.5 ($1500 * 0.005) worth of ILK. Using a 0.01 ILK/USD exchange rate, the loan creation fee is 750 ILK. In case of a loan with 4% APR, the interest is $4.93 for the full duration.
