We know Bitcoin is a volatile currency so one should not take a loan to invest in Bitcoin. If taking a loan, you will have the pressure to repay the loan and also pay high interest, which can be difficult for you to hold the investment for a long time. And there is no guarantee that you will benefit, so it may be that you may need to sell the investment at a loss to repay the loan. So don't regret the past, always focus on the future. However, if you want to invest in Bitcoin then you can invest in DCA method from your income instead of taking loan. Finally, don't invest more money than you can afford to lose.
