If I were in the OP's situation and could afford the loan's amortization, I wouldn’t hesitate to borrow money if I saw a profitable opportunity in investing in Bitcoin. I believe this market correction is only temporary. As long as the risks are managed, borrowing money for trading or investing is reasonable. After all, some people even borrow money for gambling, which is far riskier, yet they still justify it. So, if you have confidence in your plan and trust yourself, go for it. As they say, opportunity knocks only once.
