The GigaHash Cloud Mining Service with New Hashrate Available

6, Jun 2015

The Bitcoin cloud mining service GigaHash has received their order of 52 units of Bitmain AntMiner S5 ASIC miners and they are already in operation a few days earlier than the initially promised date of no later than June 9th. Currently there are more than 48 THS worth of hashrate available for purchase as some of it was already purchased by users on pre-order. So at the moment the total Bitcoin mining hashrate that the service has is about 210 THS for Bitcoin mining. If you are interested in purchasing some hashrate at this smaller European mining operation you can now do so with a price of 0.00157500 BTC or about $0.37 USD per GHS with an unlimited term contract (until it is profitable to mine) with a daily maintenance fee of $0.00117 USD per GHS. The daily earnings of the service have been pretty stable lately at about 525-530 satoshi per GHS in the form of dividends that are paid after deducting the maintenance fee. We don’t know about you, but we are planning to increase our hashrate in the service as so far things are working great and problem free after our initial first month of testing and we see a nice potential for even further growth.

Pre-order Hashrate at the GigaHash Cloud Mining Service

The GigaHash Bitcoin cloud mining service that we have started testing about a month ago has recently sold out their GHASH2 batch of 50 THS hashrate bringing the total Bitcoin cloud mining hashrate sold to customers to 150 THS. Since they are waiting for another 60 THS worth of mining hardware to expand the mining farm to 210 THS they have just added a pre-order option for the new hardware consisting of 52 units of Bitmain AntMiner S5 devices that are expected to be available and running before June 9th. The pre-order price is currently set at 0.00152500 BTC or about $0.36 USD per GHS for the upcoming hashrate (maintenance fee is $0.00117 USD per GHS) and you can already order. Do note that the GHASH2 batch 2 Bitcoin cloud mining hashrate will not start mining for you immediately, it should when the hardware arrives in about two weeks from now! So far we are quite happy with the performance, reliability and profitability of the service, so we do plan to invest some more into hashrate with the upcoming new mining hardware.

BitMain Announcing the AntMiner S5 Bitcoin ASIC Miner

25, Dec 2014

bitmain-antminer-s5

Bitmain has announced their 3rd generation Bitcoin ASIC miner chip – the BM1384 in conjunction with its 9th product – the Antminer S5 and is getting ready to start shipping the device before the end of the year. The Antminer S5 is the successor of the S3 and the S1 before that, building and improving the design of the previous generation of miners offering higher performance with lower power consumption thanks to the new BM1384 ASIC chips. The Bitmain AntMiner S5 should offer 1155 GHS hashrate with 590 Watt power usage at the wall according to the specifications, though that value may vary based on the power supply that you may pair the miner with (power supply is not included). The first batch of the S5 ASIC miners costs $418 USD and should start shipping on December 27th, the second batch is slightly cheaper at $413 USD per unit and should start shipping on January 4th 2015 or a few days later.


BitMain AntMiner S5 Specifications:

– Hash Rate: 1155 GH/s ±5%
– Power Consumption: 590 W (at the wall)
– Power Efficiency: 0.51 J/GH (at the wall)
– Rated Voltage: 12V
– Dimensions: 298 mm x 137 mm x 155 mm
– Cooling: 1x 12038 fan
– Operating Conditions: 0 °C to 35 °C
– Certified By: FCC / CE
– Network Connection: Ethernet

What seems to be the most notable change in the latest design used by the S5 is the fact that now the miner has the aluminum heatsinks placed directly on top of the ASIC chips, unlike on the previous miners where they were on the back of the PCB and thus were not so effective. This new cooling design is supposed to provide the same cooling efficiency on the new miners that previous generation that had lower hashrate and power usage.
