POOLHASH Technologies Limited were involved in FGPA and ASIC mining back in 2014 by doing it internally at their headquarters. Due to their expansion in 2016, they hosted their ASIC miners offshore at one of the rented datacenter in Reykjavik, Iceland managed by a group of cryptocurrency expert.
By doing this expansion exercise, they now have the capability to open their Bitcoin / Ethereum mining service to others by leveraging their hosted mining utilizing a cloud technology.
As per now, their hosted mining rig ratio between their own equiment and rental were 1:8. Cooler climate condition in Iceland, enabling us to lower their electricity usage for equipment cooling. Datacenter that they rent here in Reykjavik powered by Geo-Thermal energy running at 24/7.
Right now most of their mining rig consist of BitMain AntMiner S9 and S7 running concurrently with HashCoins Uranus Miner. They also have some old KnCMiner and AntMiner S5 mining at a lower pace. To operate mining, they are using several pool concurrently including GHash.io, F2Pool, BTCC, Slush and Eligius. Starting July 2016, they managed to mining Ethereum via ETHASH with our custom rigs using ethOS.
