A single antminer S9 can currently yeild  ~0.02341693 BTC. So 1,000 s9's running without any down time, in theory should yield 23.4 BTC each month.  

This BTC is split between the team and token holders.  With token holders supposedly getting 50% as the "investors profit share".

23.4 / 2 =  11.7 BTC
So 11.7 BTC for the token holders  each month.
11.7 x ~11,000 USD  = $128,700

Coinmarket cap shows a circulating supply of 15,724,272 ROCK2  tokens.

If we assume that all 15 million are held by retail  and get a portion then

128,700/15million =  0.00858 cents USD per token held

Assuming you hold 1,000 ROCK2 then the dividend yeild is $8.58.  

How is my math?  

The fact that IRM used "puffery"  (its is a legal term) in its ICO is nothing new. Many over promoted their ICOs to generate interest. Not saying it was right or ethical (from a business viewpoint).  And lots of mis-information as I do not ever remember IRM PROMISING massive ROI.  There calculation was correct based on a series of (flawed) assumptions. If anyone actually believed their ROI calculator that was not set up in real time then they were not thinking very much about their investment (ie. they clearly "cherry picked" the best numbers to vastly inflate the predicted static ROI).  There is the old saying, "If it seems to be too good to be true, it probably is".  

Does all the BS and questionable management from IRM matter to me.... Not really as all the other coins I hold pay me nothing.  For me this is a longer term hold, I will exit with a profit eventually. Simply by buying more ROCK2 with each month with my earned dividend I am slowly  dollar cost averaging down. I will eventually escape this crypto trade with minimal losses. Other than constant complaining what is your strategy to leave this trade with profit?  If you are focussed on everything the company is doing wrong then you are a poor trader as you aren't focusing on your money and your exit strategies... nothing else matters.  Good luck.
