What do you think about my idea?

[CazyCTRL]

Hello,
Recentlly I have thought of an idea. I would become a so called "bank". You might be wondering "what does that exactlly mean?". Well,i would lend my money to other people. Here is an example:

Jeremy borrows 10 k from me. I give him 20 persent interest rate.There is two scenarios this could play out:

A) He gives me back 10k with 20 persent interest rate(2k).
B) He does not give me the money back and is in violation of rule 1.1.1

I am not sure if this would be safe to do.
Tell me your opinion!
