Always a great idea to take a loan, so money you already don't have, invest it in a highly volatile and speculative market in the hope of getting enough to pay back the loan and still make a good profit. No, seriously ... Dumbest idea ever. You only should invest what you are willing to lose. When you have no money and decide that you have to take out a loan to invest in cryptos you should better start setting the right priorities in your life and learn how to handle money.
