I can see the point of a "lender".
You give bitcoin with a guarrantee and some days later you earn x% of what you give.
Zero risk for you only gain right?
Totally fine with that.
But....what is the point for a "borrower" to ask for a loan and to have already other currency?
You already have the money where is the problem?
Open an exchange account and sell your currency for bitcoin.
What am i missing?

Sorry i'm trying to understand.
