RightBTC margin account Interest-calculation rules: simple interest shall accrue on an hourly basis, if it is less than 1 hour, it will be counted as 1 hour. Interest is calculated once at the time of the successful advance of the relevant Margin Loan, it will be counted as 1 hour immediately after the borrowing is successful, and it will be counted as 2 hours after the next full hour.
The calculation formula: I (interest) = P (borrowed money) * R (Hourly rate) * T (in hours)
If hourly rate is 0.02%, for example:
Trader A borrowed 10000 USDT at 10:10 am and repaid it at 11:10 am. So the interest is: 10000*0.02%*2=4USDT
