It wouldn't surprise me if he comes back in several weeks and apologizes for not being in contact.
One thing is not being in contact and the other is stop mining ( at least to the BTC address of the group), every day our miners are not working , the ROI probabilities are getting darker.
Hopefully you and others who invested get back what they put into it.
This is the very reason I would never buy hardware and have it hosted by a 3rd party. If it isn't in your possession there is a good chance you will not be able to obtain what is yours.
I'm not very keen on CH's words/promises but I suspect he may do the right thing ......someday...even if it takes over a year.
But then again for it to take that long is to say he isn't doing good by his promises and the "right thing".
How long has mining been offline?
