Re: Why so many Antminer Z9 Mini for pre-resell on Ebay?
Because they realized they can make more flipping them than mining with them... 
Its a new device... that makes no sense...
1st batch is $1000 with PSU... so, flipping it for $1500 is better than mining?
It was $1999

Mother fucking flipper are putting pre order for august batch with their margin. They are middle men for idiots who don't know they can buy directly from bitmain at a lower cost
Example :

But if people are stupid enough to purchase a used product with almost no guarantee that will have a ROI even longer than a GPU and that will kill the network, why not profit of their stupidity ? Right ?
Ok then... even for Aug shipment... do these asic miners not even make $200 over ROI? what's the point even making them....
