OP is 17 yrs old kids want to make money quick

you ask investment advice and now you want to be proud owner of scam coin get real

Ok, so I have £1500.
I am 17 years old. I want to make money...
I have three weeks of summer left to do it.
I know that buying and holding Bitcoin is almost guaranteed to make me money in the long run but, I need more money than I already have.
How do I get 10x returns in three weeks?
Altcoins? ICO? Buy a Bitcoin ATM? Create a cryptocurrency myself?
Thanks
