Investing loan money on cryptocurrency or any other speculative assets is not a good idea, no matter how good the current market is performing. Only invest money from your extra savings not even from the salary which maybe needed for your next month expenses, make sure that you no need any money from your investment at least for 2 years to make something from the invested capital.
Loans to buy cryptocurrency are the biggest risk! How can you calculate all the chances of profit without even having the start-up capital to buy a small part of it? It is better to buy a little, save up for the initial investment. Than then get into a financial hole and not be able to repay the debt.
