Until the value of Bitcoin is more stable and technology illiterate people start to use it, there is no way that something like this can replace PayPal.
There is no way Bitcoin will ever displace Paypal without serious, fundamental changes.
Would you place much trust in a platform when you have absolutely no idea where it came from or what the motivations behind it might be?
But third parties can still verify is security.
Bitcoin was created by "some guy" that, if anybody knows them, nobody's talking. Illegal, underground money lenders are more above-board than this.
