I don't understand how you figure the amount of coins you hold affects your ROI it shouldnt.
Because the payments for mining are based on the amount of ROCK2 that you hold.
So if you hold say 1000 ROCK2 you will get at most ($1.20) per thousand tokens - Per Month! And when they add the 1500 extra ASICS which are yet to be purchased and delivered that will then increase payments 3 fold so you are likely earning $4.60 per 1000 tokens - Per Month! (LOL)
So if you were to purchase 4000 ROCK2 tokens now @ around $0.30 it would cost you $1,200.00 to earn (AT MOST) $4.60 or $5.00 per month until more miners are purchased that is not taking into account difficulty rises.
What they also neglect to inform investors, although most should know is that there are 15 Million ROCK2 circulating, so everyone needs to be paid their share via smart contract.
Unless you own 100 to 500 thousand ROCK2 you will never see an ROI and even with that many once all miners are working in say 6 months then you will still not see an ROI.
They also deleted my truthful post on the main forum, that shows they have something to hide.
ROI = Return on investment since the payout is as far as i know per token you hold so if you hold 1 token or a million it will take the same time untill you get your money back.
Im glad to see you finally got what we have been saying for many months.
