I would not risk that loan over something volatile.
The stakes are high for this and your credit score would depend on how much crypto goes in couple of months or depending on the time that you are required to repay the loan.
Yup, it's best not to borrow for highly volatile investments like Crypto. it's good if predictions and analysis are in accordance with market conditions, when it wrong, what happens? The borrower will experience 2x losses, capital loss and a loss because interest is not deducted. Actually, I am a borrower, and this is bad. When we borrow money that requires interest, this can add to the interest itself which can trap us. Avoid as much as possible, because this will be very complicated. I can say this, because i have an experience with similar conditions.
