Having this small capital, for me the best and fastest way to increase your profit is to convert it into altcoins and start buy and sell. Using this method you could you double your capital in a very short time. The only downside of this method is that you should invest a lot of your time on monitoring the market. Which is pretty much tiring if you ask me. You dont really know when the price will go up or down, so you really have to monitor the market most of the time.
