I think it is a big risk if you will incur debt just for cryptocurrency. There are a lot of investment opportunities and I would recommend that you invest on stock market as it is safer and more guaranteed.
Investing in stock market doesnt guarantee you profit. There are still losses in any investment adding to that investing in stock will take you along time to see the ROI or profit while if you invest in crypto currency there is a small chance that your investment might double.
There is no guarantee when it comes to investing no matter if its stocks or other form of investment.
