Although it is not recommended to borrow to invest in bitcoin, if you have a source of income to pay the loan and a lending platform with affordable interest, it is not a problem. Because there are cases where investors who see the opportunity to invest in bitcoin then mortgage their cars to the bank or borrow with their savings as collateral with an interest of only a few percent, and then invest the money in bitcoin, and after a while he finally gets the profit as he expected first.
The point is how you can use the debt as you expect, have the ability to pay the debt, and consider the very low interest rate, and most importantly not from loan sharks. If you can utilize debt well and have good financial management, borrowing to invest in bitcoin should not be a problem.
This strategy of yours sounds so pleasant, but it's not ideal to carry out such action. Borrowing to invest isn't proper in any sense, as it has a way of destabilizing ones financial life. Imagine after investing with the borrowed money, then you get paid in your work, instead of making proper plans on how to spend the money, you first start by repaying the borrowed loan with interest. So, In a proper sense, you should invest what you have, and not you borrowing at all time to invest before paying back.
This is why we encourage the DCA strategy, where an investor chooses a certain amount as investment funds, for a certain number of days or weeks, but it must be done continually, so as to buy and accumulate good amounts for the period of investment. You can choose to invest $20 every two weeks or month. It depends on how much you can invest and when you can invest it.
