No offense but it's completely not worth it to start trading with that amount. Getting a sizeable profit in trading needs time and your profit depends on your investment, with only 50k satoshi you'll be wasting your time for few cents.
Yes right 50k satoshi values almost nothing.Now days recommended transaction fee is around 50k and with faucets you cant earn more than that.May be getting 50k satoshies would have costed you alot of time.So i would advice u buy atleast 0.1btc and then think about it.
