If I borrow, lets say 20USD, I pay it back as 20usd, but I sow after that in the portal that it is 20-1 = 19 usd, how can I complete the missing 1 usd, can I pay a bit more to cover the extra, and what happens with the extra paid?
Got answer from AI says the extra is used as fee. So if someone knows that is is possible to regain, please give me a suggestion, otherwise I see those extra as contribution to this great platform
