To take out a loan write a comment containing:

If the bank decides you're eligible for the requested loan, it will be awarded as a bounty on the respective comment.

 with a note specifying which loan you're paying back. You can do so 

"I've read and accepted the terms of the loan. I'm requesting a loan of 10023Ṁ that I will pay back by 02/01/28, 10:02, UTC+1."

"I've read and accepted the terms of the loan. I'm requesting a loan of 10023Ṁ that I will pay back by 02/01/28, 10:02, UTC+1. This request expires 02/01/24, 15:02, UTC+1"

f(1000, 1 day) = 1000*1.00001^(24*60) = 1014.5041064170471 => due amount is 1015.

f(1000, 1 week) = 1000*1.00001^(7*24*60) = 1106.05485111179 => due amount is 1107.
