The funding round, which raised $20 million, was closed in less than a week and will be used to roll out Bitfury's 28nm3 ASIC chip4. For comparison, KNC's Neptune, while more efficient5 than Bitfury's 55nm chip, is already using the 28nm process. The BitFury roadmap includes plans for sub 0.1 W/GH chips by mid 2015.
BitFury also runs its own data centres and the raised funds will be used to expand capacity to greater than 100 megawatts. With this scale advantage over competitors, BitFury will continue to sell at least half of their hashing power to current and new customers.
One such customer is the Australian stock market listed Digital BTC6, which purchased mining hardware from BitFury in March, May and August ((March and May purchase was a $2 million investment, August was $1.3 million.) of 2014.
