you completely glossed over paypal man.
like, someone could gain reputation in under six months and start buying lots of btc over gox price and then yank it alllll back.
How would you go about doing this?
Let's say I used my Business Paypal account and started buying $1000 worth of coins a day tied to my AMEX. Do you really think if I charged back $180,000 on my AMEX 6 months later Paypal would just let it go? I would be sued in big boy court and go to prison.
These people are using stolen paypal accounts. That is why every single long weekend holiday they come out of the woodwork. The scammers know that most likely people are on vacation or not checking their email/paypal account.
There is no way that paypal is safe for buying or selling BTC.
All I am saying is that a good first line of defense is to say "Show me the coins".
