The mining process is typically in ´red´ (losses, even if it's somehow possible to mine day on the fly checking prices) therefore the miner hopes into a price rising otherwise he will just wait and buy. The pure mathematical correlation is hard to find. It´s true. right now I'm trying to see if...
Maybe you are right, but mining is a sort of barometer of the future market prices. If the hardware optimised for X11 is not fully there, is maybe for a lack of market. "Egg-chicken" dynamic. Anyway, these charts are pretty interesting.
This is a pretty bad sign. A quick comparison with the trend of other cryptos (btc i.e.) shows that there is a partial lack of interest in mining DASH (and other coins).
