There are a few issues with this. The first is that the account acting as an escrow will have to have a business account. There will be transaction fees.
Second, many small transactions can trip an alert for fraud. The account could be locked for weeks during an investigation. During that time no funds go in or out and a secondary PayPal account is not allowed.
PayPal isn't as friendly for international fund conversions from what I saw. Others may be able to give a more definitive answer on this.
I get that Bitcoin isn't "big" like PayPal, but a lot of sites are bringing it to their platform. Etsy is the biggest I can think of right now that I've used. It takes a bit of trust from each party but it can work out so much better for everyone. Yeah, sellers will still have my info if it isn't a digital purchase, but for digital purchases they don't have my information stored on the sale and the transaction sites.
Why not a personal account? And what are the fees for buying bitcoin? Perhaps we could combine transactions.
Perhaps a fraud alert could be a problem but we'd being with one transaction and slowly increase. I doubt that would flag up on their metrics. We could also switch to a dedicated account.
I agree that bitcoin is easier but I'm more concerned about getting new users now. The sooner we can get this moving, the better. Problems can be ironed out as we go.
