Follow Franky1's advice. Doing it anyway may allow you to get some BTC for the time being, but it will not end well.
That OUGHT to be good enough; the main consideration is that your bank allows you to transfer out the funds required... once you have the BTC... divide it up and stick it in offline wallets right away. Once funds are in an offline wallet; they should be reasonably secure against any 'shenanigans'.
Do any trading to fiat virtually on different exchanges that are not linked to a bank account and that you didn't wire funds to; expect to convert back to BTC before withdrawing.
Wait 1 year, until you are 18, before attempting to cash out any BTC back to real dollars.
