What I meant to say is that even if OP borrowed money for buying Bitcoin, it wasn't a wise decision. Only borrow money when the situation calls for it. I know that even billionaire companies take loans, but it is going to be a very different case for an individual who did not even manage to make enough savings for buying Bitcoin.
Bitcoin's price could remain low for years. It is possible that one's Bitcoin investment does not yield any ROI for years. What will happen if a person who does not have savings and borrowed money to buy Bitcoin suddenly lost his/her job? Or what if an emergency arises all of a sudden? What is he/she gonna do? Sell his/her Bitcoin at a loss? Loan more?
