Is it just one coupon per miner or can you use several?
How do you redeem those anyway?
All sell them because they can not be used by normal buyers.
Only 1 can be used on 1 order.. And u can not buy power source with it.
So useless.
Only big investors will be able to use them... if u buy 20 antminers and u willing to make 20 orders for them then is 100% win for you.
