Mainly for mralex. Many people use different forms of payment. As you know you can not have paypal, unless you have a credit card. This to me is a problem, most people my age dont have credit cards, but i have recently found out that Bitcoin is the same except no cc, just a proposal too add Bitcoin to the payment forms. That is all
the problem with bitcoins is that it has no same value it changes everytime, and the are ways to get black bitcoins(fake), this makes it a unlikely payment method
well i dont know about american banks, but in europe you can just transfer money to your PayPal account from your bank
