Borrowing money to invest in bitcoin, I’m also not advise investors to use that strategy to invest, due to pressure of paying back the money you borrowed, when you know that bitcoin investment is a long term investment, and there’s no also guaranteed for profit. As an investor, if there’s no any other way to pay back the borrowed money, I don’t think it advisable to borrow money to invest, because it will be a total risk to your investment, it may not last as you plan. And again instead of saving to invest in future, why not just use small you are saving, to just start direct, since there’s no amount to start bitcoin accumulation, as little as $5 you can start gradually before you realize you are have build a meaningful bitcoin position without putting yourself in any unnecessary pressure of borrowing.
There is nothing wrong if someone has source of income or a means through which they can use to pay back borrowed or loan money but it is not advisable when you don't have means of paying back. However, greed is what always makes people to borrow when they don't have a means to... And it is very wrong to competite with someone who doesn't give a fuck if you are investing, doing better than them or not because it is very funny how some people are competing with someone that isn't doing same.
