The % of ROI mentioned on your website is guaranteed, by law?
just asking because if this is not guaranteed the numbers are completely worthless.
I discussed the numbers with someone involved in industrial mining today, who says that these numbers (as stated on the hydromining site) are impossible to achieve by any means.
Nobody in the world will guarantee you any such returns. The numbers come from the return that has been achieved in over a year of operation, but HydroMiner doesn't have any influence on the future price of ETH and the increase of mining difficulty.
