Dear Sir,
We accepted escrow in the past, but several times, the buyer receives the miners, use and overclock them for several day and then return them back to us and claim back the money from the escrow.
And graphic cards aren't overpriced and we offer escrow for it.
We are keeping our post for our updates, keeping it short.
So we answer every question personally and then delete the post.
And we state in our thread that we don't accept escrow for bitcoin miners.
This is not a scam, but we have been scammed by your so called trusted escrow
