But I will never use PayPal again, that's for sure.
They can't 'steal' the money - when accounts are locked they either hold onto it for six months or require you to keep a minimum balance. This is how they mitigate their massive risk profile.
Their customer services are entirely worthless, it's true, but I suspect that anyone coming to 'disrupt' PayPal will struggle with many of the same issues because they're caused by fundamental risk issues with online payments.
In this case I was both the buyer (from my personal account) and the seller (my business paypal account - I was using my own app to register a domain).
So despite the fact that I had access to both accounts PayPal interfered and did not let either side mark the transaction as legit! Various emails to paypal later I gave up. I did everything they asked, re-verified etc
It was basically impossible to sort out either through the paypal interface, through their customer support, or by phone. At least I know what my customers go through... bye paypal.
If this property is sacrificed in the interest of making it difficult to 'launder', then its utility is questionable.
One of the properties of money is that it's value can be trusted. If money can be easily laundered then it can't be trusted and it's utility is questionable.
I recently had to receive a significant payment from a client of mine. It would have been convenient--and worth the fees--for me to use Paypal to receive that money. But after all the stories of frozen accounts and my own experiences, I'm scared to use Paypal for more than a few hundred dollars. I had the client send a check instead.
