Money isn't worth anything right now (beyond its face value) because we have extremely low interest rates at this time. I would suggest using it to buy some stocks in a sector you have some understanding about. If it goes well, you will know a place you can put money in the future. (This only is feasible if you can afford to lose your $870 if it doesn't go well.)

Also, if you have any debt at all (school loans, etc.) you can probably make a better percentage profit paying your debt off early than you can in any other way.
