It all depends on your knowledge of trading. When trading in the US stock market, big gains can be made from buying $200 worth of options contracts, but just as quickly as you gain, you could lose without proper knowledge and strategy.

I suggest learning all that you can before trading any money, having proper stops in place and not trying to swing for homeruns on every trade. Slow and steady wins the race.

Read up on compound interest, small gains quickly add up over time.
