http://whiteelephantmedia.com/PayPal like the mafia extorted half a million dollars from this company and then after getting it, froze their account and stole all their money. Something like one million dollars.
You could get a merchant account, but such processor could freeze your account. Tradehill had their payment processor steal $100,000 this way.
The only real way for dealing with payments is bitcoins!
Bitcoins are "a way" but not "the only way" to receive payments. It is shallow thinking to think this. Think about it.
