Invest it, in 10 years it will be worth alot mores, cause right now you don't really need it.
Maybe go on a spending spree with 1000$, spend some on toribash, and some stuff irl, other than that save and have fun!
Why $3 000 Dollars for a PC when you could have one just as good but custom made for like $300?
Whatever you do, just don't go on a shopping spree because the money will fly away and before you know it you won't have any money ._. .
