I would highly recommend getting a bank account, money in paypal isnt secure. If someone hacks you you could loose it all and if someone files a charge back you will get burned. The best way is to use paypal as what its meant to be, a gateway. Being a minor doesn't matter in terms of a bank account, if you can get a parent to co-sign for you, you can get a bank account. If your parents wont let you get one, use theirs and just know how much of it is yours.

If none of that works, wait till you have 1k and a check for it, ask the teller to get it all in 10's, come home with 100 10's and with them in your hand make the appeal to your mom or dad.
