Thats big stake to put on genesis. It is profitable currently with one year of ROI rates. But who knows what will happen with genesis in one year of time bro. You can try something else, may be put the money into your own ICO development with the help of other sponsors and get shares of the company. Just saying!
I think that is a good idea of developing an ICO and because you have received support from the sponsors. But I don't see it will stay strong as it is for the coming years due to the situation of the bitcoin economy which sometimes an unpredicatable currency. Although you saying it's profitable, but let's just accept the fact that mining is not that progressive compared from recent years past, due to it's impact to the electric consumption and how efficient it is to mine bitcoin with regards to the supply.
