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.
i don't agree with any of this, of course it is obvious that if you start with a larger capital you can make a larger profit but it is not necessary to start with a big amount especially if you are a newbie you should not start with a large amount because you will lose it and regret even doing it. but maybe start with just 2x of that amount (100K)
also you are dead wrong about fees because for a medium size transaction these days the high priority needs less than 19K satoshi and you can even get confirmation with the old 10K satoshi too.
