Borrowed $1600 from my friend. Apart from this placed gold as collateral and got $250. Altogether with hope of returning the borrowed amount and taking the gold back started to play dice after a long. At the beginning it went good, and when my profit reached $200 started to fail. Once I began to loss I was out of my control. Within minutes everything went out of my control, my mind didn't had the ability to think. I just doubled the bets consecutively. Ended with a loss. Now I was in a situation to repay my friend the borrowed amount. Please don't borrow and spend on gambling, it might give an earning, but that mostly leads to suffering. 
A lot of people already did same thing like what you did. They are really confident to use other people's money either it is to do trading, or maybe gambling. In this business, make sure you use your own money. Although you are professional in trading, don't every try to make investment or borrow people's money to increase your capital. Nobody know when they lose all money in trading . At least if we use our own money, if lose we don't neet to pay anyone.
