Never ever put at stake the money the you cannot afford to lose in a risky situation since it's volatile.

A loan to invest is a big risk and not only in bitcoin. I wouldn’t even risk buying bitcoin with other people’s money, if I could borrow money from my relatives or friends, I still wouldn’t be able to feel calm, because it’s not my money and if I lose it, I will have to give away. Investing credit money is a matter of luck, you may or may not be lucky, but I would never test my luck in this matter.
