absolutely not. there's still tons of counterparty risk with paypal.
isn't that why you're here in the first place? bitcoin's irreversible transations eliminate alot of counterparty risk.
For example, me. I need "download" my money from bitcoin to dollars or euros and the easy way to do that is to offer bitcoins for a paypal deposit. I hope that arrives the time when will be not necessary to use credit cards and bitcoin will be the standard currency to Internet transactions.
