We've switched away from solo mining for the time being, and are spreading our hashrate equally between the three largest pools: btcguild, ghash.io and f2pool (discus fish). The change was made about 36h ago, shortly after we mined our 5th solo block.
sorry to be blunt, but you look like bumbling fools. ramping up, ramping down, going solo, changing pools, testing variance. this is investor money you are playing with, or have you forgotten this?
