I think it's perfectly okay for bitmain to mine before selling and shipping. It's not like you paid them money for a preorder and they use your money to build miners, mine on them, then ship it to you months late.
Bitmain is different than other ASIC's companies. They are trying to setup a win-win situation for themselves and customers. Sounds good to me.
you are joking right? tell you what, next time you go buy a new car, just let the guy on the forecourt take it home to his wife, 3 kids and 2 drooling dogs for a few weeks first.
I can't believe you seriously said that. please keep whatever you are smoking, to yourself.
I don't give 2 licks what they do with the hardware before they ship it. If they ship it when I order it and it works and keeps working, that's all I care about.
