I wouldn't recommend taking a loan either unless the person in question is an expert who has been in the trading space and financial markets for a considerable amount of time, which makes them qualified to be able to use a loan in a good way and not waste it by trying to achieve something.
When someone is new in trading, they shouldn't think of borrowing money or taking out loans so that they can start their career in trading because what if it doesn't work out? You will get in serious trouble if you don't successfully manage the funds and lose it all without any success because you will still have to repay the loan, which you can't do if you don't have a stable source of income. Taking out new loans to repay the old ones is not a good way of managing loans.
So, a newbie in trading should only start getting involved financially if they know they have money that they can spare and can afford to lose so that even if their experiments don't work out, they should still not be in any trouble for it.
