The only aspect of mining anyone should care about is how many actual coins miners possess and need to sell. I don't think anyone should be trading based on analysing mining.
Mining was designed to take care of itself. No one else needs to care about it. If the current crop of miners can't hack it they'll leave until some others come along who can hack it. No one knows their costs, whether they're hedged, who's buying their coins or what their plans are. It doesn't matter.
true.
I even wonder why a lot of people tend to put a lot of emphasis on mining as a means of what the market value should be in the long run. Certainly at this stage a lot of the miners have shut down their rigs for now until further notice and usually, the network has been designed to correct itself with increase or decrease in difficulty as the case may be, so one way or the other, I simply will not see that as a problem for the bitcoin network at all.
