If you borrow money from someone, do not use it to trade or gambling. It will be like you can make money from it within a short period of time but the money will be lost within a short period of time instead.
$50000 is enough to start a good business. Why trading? All I see about it is someone that is not patient and looking for fast money but instead he got into trouble.
This may not be true but there is possibility that something like this can happen.
If not for greed tell me why someone will borrow $50k for trading and the problem with this kind of people is that they are always occupied with the mindset of making quick money that is why they don't even have the consciousness of the huge amount they are using to trade. We all know how much $50k is in Nigeria, with that amount one can even set up different businesses that can at least generate a profit of $3K monthly, such that after paying up the loan the business will still belong to him. Don't be surprised that this may not even be the first time of borrowing such huge amount, maybe he got lucky previously and decided to try again.
