To make an informed decision, "#3" would need access to at least one of the two involved Paypal accounts, right?
If it really comes to that, I will let #3 login into my Paypal account. If for whatever reasons this is not possible, consider me as a fraud and #3 should decide in favour of the seller.
My point is: I wouldn't want to login that way, as it red flags my IP (and my own Paypal account).
Chances are 1% of 500$ is not enough to pay the fee
Fees are payed by me. #3 receives 1% of the total involved BTC.
In December, that would have been 0.00025
BTC, while fees were about 4 times higher than that amount.
Also I was looking for the chargeback period and didn't find anything useful yet. Do you have a link to that 180 days?
A quick search shows
this and
this.
I'm not sure what the limits are if stolen creditcards are involved, but it's safe to assume they'll go after their money as long as they can.
You should be much more careful who to trust.
That's a good point. I really have no idea what criteria would be sufficient. What would you consider trustful?
Users have trust ratings, although some can be fake, and not all transactions lead to a rating. Reading someone's trust (including "untrusted feedback") and reference links is a good start.
Don't just look at green trust, read what it was given for.
