The Japanese GMO Miner B2 is Sold Out, Here Comes the B3
While still in pre-order stage the first 7nm ASIC miner for Bitcoin (SHA256) – the 24 THS GMO B2 miner has been sold out. The Japanese company behind the project however is apparently ready with a successor – the GMO miner B3 that will be offering variable hashrate of 24-33 THS with 1950-3417 Watts of power usage respectively at the same price of 1999 USD. The new miners will come with 180 days of warranty and the price includes a 4 kW power supply as well. GMO is already taking pre-orders for the new B3 miners and you can pay using Bitcoin, Bitcoin Cash or USD with shipping expected to start in November 2018.
The new GMO B3 ASIc miners come with the same base specifications, but there is an extra that allows the device to either automatically adjust performance or the user to optimize it so that it can reach up to 33 THS hashrate with reduced power efficiency. This feature is interesting as it will allow miners to increase performance at times when there is higher profit to be made and to reduce it when the profit is not that good. The extra performance at the same price as that of the original B2 miners does seem like an interesting upgrade, especially considering that you get an adequate power supply also included in the price.
