If you lose money risking $50 per trade, you'll lose money risking $500 per trade... at least on the $50 you'll live longer and you might actually learn how to make money.
Get a visa for the hottest Colombian chica you can find and rent her out by the hour to your buddies. You will turn your 50K to 500K in 2 years.
Postpone college for a year and take a part time job. Use your free time to learn how the market works by reading everything you can get your hands on. Conservatively position trade the 50k on the side. By the end of the year you should have about 80k from the money you saved at the job and the profit from your trading. By the time you go to college you're going to really apply what you learned by transfering 30k to a margin account to trade futures. Use this account to generate the income for a very comfortable college lifestyle. Let the remaining 50k grow and use it to pay off college or as a future downpayment on a house. You can apply the knowledge you gained to land you a good job in the sector after college.
