Since you are new I will explain it to you.
Bitcoins are not reversible.
Every form of fiat money is reversible except cold hard cash.
Since credit cards, bank transfers, and especially PayPal are all reversible nobody will accept your reversible payment for irreversible Bitcoins unless
you have a very high solid reputation (not the other way around).
So come up with a more cash like equivalent (MoneyPak, etc.) because nobody will trade with you for a reversible payment. Period.
Now the easiest way to buy Bitcoins is to get some cash, join
https://localbitcoins.com, find a seller in your area, meet them in person and swap your irreversible cash for the irreversible BTC and everyone is safe and happy.
BTW anyone who has been involved in Bitcoin for any length of time can tell you many ways you can be scammed because most of us have been scammed in the past by people just like you (noob that just wants a small amount of BTC for a reversible payment method).
