For anyone still in doubt, I can confirm that it is, indeed, a SCAM.
See his post on reddit:
We're currently about to close the sale of a whole first batch of devices to a private investor. We will be required not to duplicate the device for at least 3 years. Sorry guys. We will eventually refund all the people who sent the 5 btc within 48 hours.
And just last night he sent me an email:
Hello,
Thanks for taking the time to write us an email.
We will have a couple devices left to sell.
Entry level device with 2 boards price breakdown :
Controller device $150.00
ASIC board $250.00 x 2
Shipment $50.00
Total $700
Full device with 10 boards price breakdown :
Controller device $150.00
ASIC board $250.00 x 10
Shipment $50.00
Total $2700
The case will be similar in size to a mid-tower standard PC and you will
be able to purchase 8 additional boards if you decide to go for the entry
level machine now, sorry to inform you that, in that case, there will be
one more charge of $50.00 for shipping.
In case you decide to go ahead please provide details of your order, your
full name, address and valid phone number along with the 5 btc transfer to
1FyZ3qU54jxU5tF2KHxHmnyjkAsdWuiyFr
We will let you know when the production have actually started both via
email and our blog.
Best Regards
Asicminer team
Now why would he be refunding 5 BTC back to everyone if he still has a couple to sell??
Anyone who gave him 5 BTC - you will never see it again. So don't hold out any hope.
