The joy in trading is when the money which is been used to trade is owned by the trader. Normally trading is something that is unpredictable, one can't really know or see the outcome if it will be a big loss, small loss or big win, small win. When money that is been used for trading is owned by the trader if there should be loss he may not too feel about the loss, unlike when the money which was been used for trading is borrowed, in a case whereby the person do not have good source of income.
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.
Borrowing money to trade or invest in crypto is highly discouraged in this environment, I personally have had good opportunities to borrow money to invest in crypto but after weighing the both sides, that's profit and loss, what I stand to gain and loss, I refused to take the loan.
Just like some guys already said here, borrowing money to put into crypto investment or trading already takes away your peace of mind, it will cause one to live in constant fear and anxiety of what if anything goes wrong for whatever reason beyond your control?
The truth is that it is better to trade or invest with your money than borrow to do this, cus the restlessness and health challenges one would pass through before the gain even arrives is capable of shortening ones life span, so I highly discourage borrowing to trade or invest.
