[versterk]

Hi there

As I've bought a lot of antminers S1 and S2 , I have a big buck of coupons today

and can't use 'em all

so if someone want to get some , I'll be happy to sell them 

values are $400 for S4 and $50 for C1 / S3+

thank you for attention

These coupons are/were free, just so everyone knows.

are you telling us that bitmain is scamming previous custommers ?
