Definitely a scam, the only way you can use the coupons for other people is to buy the miner for them.
As said you can't sell the coupons to use on other accounts.
First. I don't appreciate you calling me a scammer, because I'm not. I've only done things on these forums to help people.
Fix machines, give advice, etc. So please - have some self-respect.
You've certainly posted 2 or 3 helpful comments in the 33 posts you have done so far, no dispute there. You've also spent enough time in the Bitmain thread to know that you can't do this:
Here's how this will work.
Private message me the coupon you would like to purchase.
I will reply with my BTC address. Send the BTC to my BTC address. Allow me at most one hour
to confirm the payment. Within an hour or less of receiving the payment, I will privately message you
with the coupon. That's it.
You may not be a scammer I'll give you that and amend my post, but it needed a strong message to stop anyone sending you any BTC which might make you into one.
