I know someone who started how to trade about four months ago. He is a beginner in trading, I don't really know how good he is, but to him he may feel he can always make earnings. I think he was so confident in himself, he had to borrow money for trading which he could not make good profit. As a beginner borrowing money to trade is not the best. It is not even advisable to use all the money one has to trade or invest talk much of to borrow to trade.
Do not listen to anyone who doesn't understand how loans work. If you end up getting a loan and buy bitcoin with it and assume that the increases would allow you to not only make money but also allow you to pay your loan back, then you are an idiot. However loans are out there to improve your finances, is there a method you can get a loan, use it on crypto, and improve your finances? That means you should take it.
Coinbase took out loans in sizes of whole neighborhoods real estate value, did they fail? They did not bankrupt right? Well, not so far. Look at Wall Street, there are banks that got billions, the whole loan was 800 billion I believe, and they get cash injections in billions every day. Just know why you are getting a loan, if it is a stupid reason then don't get it, if you can justify it then you should get it, that is how the loan world works.
