I offered .3 BTC and he said deal. When I suggested to use an escrow he told me no thanks. Warning. This is a scammer.

me: can you do .3 BTC for a S9 without PSU?

seller: Ok, I'll do that.
me: cool. you okay with using one of the top 3 escrow services on bitcointalk?

seller: No, doesn't my ad say I won't send my miners to random third party? I can send you a pic of them with your name written on a piece of paper. You can order from bitmain directly for December shipment and bitcoin cash payments only. They got on their website now.

me: the way these escrows work is I send the BTC first to the escrow service. the escrow service confirms the BTC is there, then you send me the miner. once i confirm the miner arrives, the escrow service releases the BTC to you. It is pretty standard. No one will make such a big purchase without some sort of escrow service.

seller: No thx
