How to get Bitcoins without having a bank account? I'm an 18-year-old guy who wants to get some bitcoins but I don't have a Bank account yet.

I've been looking at some websites, such as bitstamp.net or blockchain.info but they seem like they are having problems (each one with its own problems).

What would be a fast way of converting cash into Bitcoins or cash into PayPal into bitcoins? (I don't know wich method can be used to get bitcoins, I'm really new to this.)
Read up about chargeback, this is unfortunately a huge problem when you exchange from bitcoins to 'PayPal dollars' and other online currency.

However, you can buy bitcoins with cash: https://localbitcoins.com/
