This is my second thread(the first one is deleted) about how to calculate profitability on a cloud mining site.

As they strictly avoiding to answer for any questions about profitability,and they are providing super vague answers.
I purchased a few contracts there to see how things are going before I send more btc in.

Now I'd like to conclude it somehow,that this  cloud mining company is a decent one,just they have a very bad and rude customer support.
Or this cloud mining company is a Ponzi scheme
All of this without to name them first,just to keep the biasses as neutral as possible

As a beginning here is the original thread salvaged and uploaded in PDF:
