It is not recommended that loans for investment be made from profits, because they may not always be able to produce profits on time, resulting in the burden of not being able to pay the loan.
The market is highly unpredictable, and borrowing money with the assumption and intentions of repaying the loan with profits gotten from the investment could all end in absolute disaster, because one cannot accurately predict the market, no matter how good your speculations have been and how correct your previous predictions have been.
Something could happen at anytime and the market can end up in a DIP when the repayment date becomes due, forcing you to sell in a DIP in order to repay the loan, thereby resulting to even more losses.
It is not recommended to borrow for investment with the aim of paying it later from the profits, because we cannot know when the profits will be obtained, while the loan must still be paid. Of course, this action cannot provide a guarantee, but if you have the ability to be able to pay the loan installments from income from a permanent job, of course, it is highly recommended that you do this.
There are many examples of companies taking out loans to increase their investment, but the loan installments can always be done well.
Don't be afraid to borrow if you have the ability to pay in installments and there's no need to be afraid, because crypto investment is very good and really profitable.
