If I am expecting money trust I will wait for as long as I can to get this money before investing in Bitcoin perhaps it wasn't a matter of life and death so i will never try borrowing to invest in Bitcoin for any reason.
I definitely appreciate your idea. Because if you are not in debt, you can be calm mentally. But those who take loans have to go through mental stress. I personally do not like taking loans if there is no need for it. However, not all investors have the same financial situation, and not all have the same mentality. If an investor is such that he is investing in Bitcoin for the long term, especially doing DCA, but suddenly for some reason Bitcoin falls drastically and at that time if he borrows money for the purpose of investing a little more with risk, it may be a good decision. However, in this case, he must understand whether he will be able to repay that money or not. If he has a different source of income, then it is not bad to take advantage of a good opportunity by borrowing money. However, this strategy does not apply to everyone. A common advice for everyone is that if the investor has a long-term DCA and can make aggressive investments with some of his discretionary income, then it is definitely acceptable. The opportunity to buy from the dip in Bitcoin will not always come, so it should be used appropriately.
Where most investors gets it wrong is from the beginning, they think that the loan will be repayed back from their Bitcoin investment, without paying attention to little details that it will be repayed back from another source.
Additionally, once it's a loan that can be paid back in installment manner, then taking a loan is not too a bad idea, especially if the interest rate is very low, because part of the borrowed money can be paid monthly once you receive your salary, before you will know it, you will be done repaying it.
