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.
Borrow money from your pal and trade, I don't think it's a good idea because there's commonly alot happening in the space. We're not newbies in the system and we know how volatile it gets, we should just play careful amd become independent with our trading pattern. We should also learn to accept losses, take correction and also doing what is best.
The amount mentioned is quite reasonable and we should always put ahead risk management in the system. Don't get it twisted because alot have happen, we learned from our mistakes and lessons. To be successful in the trading space, apply learn, practice and process it.
