The initial reports they weren't able to pay ongoing claims due to not hitting an ethereum block demonstrates they are severely underfunded and relying upon incoming deposits and luck. The fact they suddenly run into problems the moment the market turns down seems like no coincidence. Many people predicted these same things years ago. How they would ever be able to handle users stopping 'reinvestment' and then withdrawing en masse remains shrouded in mystery.
Watching the mental denial process of people participating in a true Ponzi is mind boggling. Like drowning swimmers they'll lash out and try to drag down the people trying to save them.
This is the truly obsurdly enormous red flag, at the very least, they sold more hashrate then they have mining... for the sake of the arguement, assume they have the mining facility they have claimed to have.
They claim to have the largest ethereum mine, they claim to have 200,000 customers... if each customer only put in the $30 minimum for 1 MH, then the facility is producing at least 200 GH... does it make sense that a 200 GH mining facility hasn't hit a block in a month... 2 months... 6 months (the article I think said since Feb.)
Either the report is full of it, or GM.
Regardless, having issues paying customers/contrators/suppliers is never a good sign for a company.
