I agree for those who are mining at a larger level (i.e. all those mining in washington) who are taking the local electrical authority beyond its capacity because of the cheap electricity which is a byproduct of companies taking over what was supposed to be a de-centralized activity.

1 word.  Greed.  We all have some sense of it.   For those who were in for a long time, maybe not....but when the buzz words are "moon" "lambo" etc.  makes you wonder. 

I think a lot of money flowed in and out kind of like a Tsunami wave from December to January. 

It was flowing in from the ocean rising the tide (i.e. bitcoin)  and then hit a critical mass (December) and flowed over the banks into (altcoins) and then receded back into the ocean.   I don't believe there will be another tsunami like that for a while.  I'm just paying off my miners with 75% of profits and 25% is holding.  It'll be a while, might as well hold some.
