I can escrow the transaction, I have an account on Bitmain ready to receive the coupons, I am an established member in this forum, and I am an admin in the bitmain coupon group on telegram https://t.me/bitmaincoupons

I will need to read the terms of the deal, and the following must be provided.

- The BTC address of the seller and the agreed amount
- The Bitmain account email address for the receiving party

The process goes this way

1- Escrow fees sent to my address.
2- The seller sends the coupons to me, ones received, I will inform the buyer to send the funds to the seller.
2- When funds arrive (by checking on-chain data) I will transfer the coupons to the buyers account.

I bought and sold thousands of Bitmain coupons in the past, things can go wrong, and it's a sort of a hassle escrowing that, so fees will be set based on the transacted amount.

If you agree with my terms, reach out via a PM.
