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.
Everyone has their preference, some people might have such an amount and decide to do a business with it while others will choose to fund their trading account with it.. it's all a matter of what interests them and what they are good at..Not everyone that starts a business with that amount will end up succeeding, and not everyone that decides to trade with that amount might end up making profit..life is about finding what works better for you
