Let's think about it, dude. Why not zeus selling mining rigs ? You hear the voices of a desire of Volcano or GEN III Chip Blade? Many people cant wait to upgrade their rigs with a blade. And Zeus can earn the reputation from it and honor the delivery term. The premise is that they Really have Volcano and blade!!! Why would zeus prefer to offer a refund rather than ship out miners? The answer is : they've never produced it at all !!! A manufacturer will never risk itself breaking its promise. Besides, honestly with the price of coin right now its not worth the investment in any mining hardware considering how much it cost.
