You can start lending your $ 300 USD to get started with investment. As $300 is very less amount to trade or gamble in the first place so you have to lend it. Lending will grow your money systematically with upto 10% weekly interest on it. Thus you can easily make 30 USD per week from this method. Just the warning is that, you have to be very careful while you lend your money as it is very hard to find loyal people here. But with the help of collateral and escrows you can make it happen.

Once your money grows you can just use it the way you want.
