Re: Contracts for the purchase of BTC. Any purpose of payment.
I sympathize with you that you have encountered scammers. But your situation has nothing to do with me. I am not the owner of BTC, I represent the interests of sellers. We do not take prepayments. 95% of our transactions are through escrow accounts. It is safe.
Nobody has labelled you explicitly as a scammer. Sure there are similarities in terms of traits though. The biggest problem here, quoting you is "I am not the owner of BTC".
Take a look around - the modus operandii of scammers are: 1) The offer to buy/sell insane volumes; 2) If they sell - they cannot sign a message from the address that hold the BTC, 3) MITM scams - where they "broker" deals but disappear with the coins + money.
Even further you state "95% of our transactions are through escrow" ...what happened to the other 5%
If its not 100% - its not good enough.
