They are probably sorting chips for mini vs full size z9. That is common for other chip makers and helps explain variation in batch one hashrate. Unfortunate for batch two buyers on all fronts, it seems.

Batch one was billed by DHL about 20 days after delivery via mailed invoice at 2.6% for me. Don't get too happy yet.

Thanks

"Tagtuyot" scammed me, they were allegedly selling coupons. This account recently had email changed. It was reported stolen on the ether address they used after I was scammed. Telegram used was @compassssion with an australian region code. A mod should lock this scammers account! Be careful of stolen bitcointalk accounts, no one is safe with these scum around.

Don't buy from "Tagtuyot" I think the account was recently stolen and I was scammed. Email was recently changed under trust. ETH address provided was commented scammed. Not sure how to contact someone to lock the account.

How does one acquire several hundred bitmain coupons? Send me a pm, thanks.

Thanks for pinning this thread it saved me from some issues. I'm sure many noobs (me included) initially find the forum because of the marketplace. I am having trouble finding legit threads in the wake of this info, however.
