I am also interested, but is it just a "send BTC and trust me" thing? Are you planning to set this up in a legal contract? How are you going to handle disputes? What if they dont deliver? What if it takes them 2 years to finally get it working correctly?
With the history of cryptos and ASIC production, this is a really risky gamble. I may join up once I hear more, but atm its just too much to loose

A legal contract will be in place. As for disputes, I make the ultimate decision as
I will own 50% of each rig. Yes "trust me" thing is in place. But you can visit the facility and meet me (southern cali) if you wish.
As for delivery of Alpha-T, it is out of my control. Refunds can be voted on an approved in which the refund will correlate with the amount Alpha-T refunds.
As with any new ASIC, there is risk involved. Hence caution, as you are trusting a brand new company.
so remind me why you are doing a groupbuy? just preorder a system for yourself. mining hosting is only a headache for everyone involved (particularly the participants who are at the mercy of the hoster's decisions/fees and who receive zero compensation for the physical hardware value when the hoster decides the rig has outlived profitability)
my 2c: buy your own hardware and save hassle. and dont pre-order stuff thats months away
