I like the idea , but you have couple of problems  .

- Isn't ICO based on mining at this times is not a good idea ! . The mining profitability is at its lowest since very very long time . How you plan to overcome this !
- The total amount from the profit to be distributed to users  is 75% ( 50% + 25% to be reinvest ) , there is 25% of the profit gone which I think will take away the low electricity and cheap operation with it . Let alone from this 75% only 50% will be give to investors . I do not understand why would anyone by tokens that will give him 50% profit while he can just order his equipment from amazon and start his own rig and make 100 % of the profit for him self . Can you please explain more what is the other benefits that will make anyone buy tokens and not buy his own rig , clearly the -25% not counted will be weighted with the cheap electricity and cheap operation ! .
