biterial.com are scammers. They stole my Btc. They do it like this: you pay him bitcoins, Btc are held in escrow (as if). Then Btc buyer ask you to send your Paypal email and then you will receive 2 transaction from different persons as if you sold ebay items. Then allegedly buyer will open dispute for refund transaction. You are forced to cash back, because paypal will held account access limited. When I ask site support to refund my Btc from escrow they demanded send him video of my Paypal: 1.login to paypal 2.check history 3. dispute details to make replacement . After some time they release escrow without my consent.
