Dosent ebay have the same policy? I heard of a few people getting scammed out of their coins because ebay reversed the transactions..

Thank you.
Just bought 1 PTS :)

ebay uses Paypal, and has tons of almost all coins for sale/auction

Thank you.

In the meanwhile I searched in PayPal and the FAQ about this subject.
For reference I am sharing the link  => https://www.paypal.com/us/webapps/mpp/security/chargeback-faq

Hi,

People don't like dealing with PayPal and I wouldn't recommend it for the following reasons:

1)  PayPal do not protect against tangible products.
2)  This means PayPal will happily reverse the transaction and PTS / BTC will be lost.

Hope that helps.

I have ~ 100 USD in PayPal and would like to buy PTS.
So far I could not track any trading service which uses PayPal.

Actually, is there any service PTS or BTC accepting PayPal ?
