This 1TH/s miner is using illegal fake A1 Coincraft ASIC based miner produced in China. They are being sold on the black market in China illegally and without Bitmine's permission:
http://bitmine.ch/?p=5178IF YOU PURCHASE THIS MINER THEN YOU ARE PURCHASING COUNTERFEIT HARDWARE AND IN MOST Countries that is considered illegal. Just trying to warn people because we have spent a lot of money on genuine A1 Coincraft chips that we purchased directly from Bitmine at the end of January and we know how much they cost. There is NO WAY that the ones being sold in China for around $4000/miner are legit. It is ruining the Mining difficulty for everyone else for people in China to be stealing Bitmine's intellectual property and selling it for less than the bulk price directly from Bitmine.ch
There is no guarantee that those chips will perform to Bitmine's standards and they are definitely NOT real A1 ASIC chips. Check the price on Bitmine's website yourself for purchasing 500 chips. Their pricing is $43,750 for 500 chips which comes out to be $87.50/chip
How can people in China afford to sell 1TH/s Bitmine A1 Coincraft based miners with 40 chips per miner running between 25-30GH/s per chip for only $4,200 to 5,000? The 40 chips alone cost $3,500 (40*$87.50=$3,500)
This $3,500 bulk purchase cost of the 40 A1's from Bitmine does not include the cost of manufacturing PCB's, cases and the rest of the parts for PSU's, cooling, Raspberry Pi, etc...
The math does not add up so I would be VERY CAREFUL of buying those illegally produced A1 chips! It is like purchasing a fake iPhone. It may work for a little while but it is not the same quality as the real thing. Help stop this criminal activity by boycotting the sale of these fake A1 Coincraft chips from China.
