Something interesting and not so nice regarding Bitmain and their latest batch of Antminer S9 ASIC miners, it seems that although the company is listing prices in USD, BTC, BCC and LTC on their website it will only accept payment in BCC (Bitcoin Cash) for the batch of miners shipping November 21-30. As a maker and seller of these devices Bitmain of course has the right to sell them any way they want and accept the payment in the form they choose, but this way of essentially “forcing miners” to buy BCC to pay for the hardware (in case they do not have it) is probably not very “politically correct”. It is understandable that they want to support BCC, but is this the right way to do it or it will fire back with users going to alternative options for ASIC miners (not that there are many available unfortunately)…

The questionable text about BCC payment for the batch is under Payment and is quoted below:

Only BCC payment method is accepted in this batch, please use the exact amount mentioned in your order and complete the payment within one hour. After one hour, the order will expire and your payment may not be detected by the system automatically. If the payment is submitted but the receipt is delayed, we will make your payment “Valid” manually.

Bitmain has announced a new AntMiner T9 ASIC miner that should go on sale today for $1104 USD offering 11.5 THS hashrate. The new miner is based on the previous AntMiner S9, though it comes with a bit less chips that are apparently clocked at a higher operating frequency. The new T9 is a bit cheaper, but not as efficient as the S9 as based on the official specs it consumes about 1450W for the 11.5 THS while the Batch 22 of the S9 came with 11 THS at 1078W and Batch 23 was with 14 THS for 1372W. The new T9 miner comes with just 171 BM1387 chips while the S9 was based on 189 BM1387 chips. The two fans cooling the new device are the same as on S9, so you can expect similar level of noise from the device. So in short the new AntMiner T9 does not in fact seem so attractive to miners, but with the lack of new S9 miners you might not have much of a choice…

BitMain AntMiner T9 Specifications:
– Hash Rate: 11.5TH/s. A variation of +/- 5% is expected

– Power Efficiency: 0.126J/GH + 7% (at the wall, with Bitmain’s APW3 PSU, 93% efficiency, 25°C ambient temperature)
– Rated Voltage: 11.60 ~ 13.00V
– Chip Type: BM1387
– Chip quantity per unit: 171 chips
– Dimensions: 350mm (l) x 135mm (w) x 158mm (h)
– Cooling: Two 12038 fans. Front fan: 6000RPM, rear fan: 4300RPM
– Operating temperature: 0°C to 40°C
– Network connection: Ethernet

One more announcement fro Bitmain, the AntMiner S9 ASIC Bitcoin miner is no official and will start shipping on June 12th for $2100 USD without the shipping cost (power supply is not included). The device uses the company’s new 16nm ASIC chips BM1387 and essentially triples the hashrate of the previous generation S7 miners while offering the same level of power usage. The Bitmain AntMiner S9 should be capable of 14 THS SHA-256 mining hashrate with a power usage of 1375 Watts at the wall, so definitely a good improvement over the S7.

Bitmain AntMiner S9 Specifications:
– Hash Rate: 14.0 THS ±5%
– Power Consumption: 1375W + 7% (at the wall, with APW3 ,93% efficiency, 25C ambient temp)
– Power Efficiency: 0.098 J/GH + 7% (at the wall, with APW3 93% efficiency, 25°C ambient temp)
– Rated Voltage: 11.60~13.00V
– Chip quantity per unit: 189x BM1387
– Dimensions: 350mm(L)*135mm(W)*158mm(H)
– Cooling: 2x 12038 fan
– Operating Temperature: 0 °C to 40 °C
– Network Connection: Ethernet
– Default Frequency: 650 MHz

The big question however is if now was the right time to announce the new mining hardware, as of you order now from the first batch you might be getting your units delivered right before the Bitcoin block reward halving. So it might be wise to wait for a later batch of S9 miners after the halving to see how the situation will change and if you might get a better deal in terms of price for the hardware. Then again if you are using S7 miners you might already get to the planning for switching to S9 now that the previous generation S5 is no longer profitable barely covering the electricity costs.
