I have (4) $220 Bitmain coupon. The $220 coupons expires on 06/10/2018. Am looking to sell and will accept most cryptocurrency. If it's listed on coinmarketcap, hit me up and make an offer. Even if it's not on CMC but still active, hit me up and make an offer. Buyer should arrange escrow with a reputable escrow or be willing to send first. you will need a bitmain account for me to transfer the coupons. Anyway, get in touch if you need one or all of this. Take care
