If you do not have enough capital, you should temporarily step away from trading or gambling and wait until you have the capital to manage. You should never borrow money from anyone or borrow money from a bank at high interest rates to invest or trade.
If you do not have enough capital for trading it is good not to make any attempt to take loan to trade because trading is not certain or it even better to trade with the small capital that you can afford, don't go with amount that you can't afford by trying to take loan some where else.
Borrowing to trade can put you into more debts if you because their are chances of losing in every trade, personal mistake is a factor and the volatility of the market is a factor and others factors. Trading is very risky to consider loan for trading.
