When you start you need to start small and with me that was the case. First i had some little trades from where i started to make larger traders.
If you follow this peace you see you can earn more and more. At this moment i have a good profit of 4 BTC.
Yes and if trading is new to you then its better to start with small amount that you can afford to loose, and after spending enough time and learning, you can go with an higher amount.
