To value a start-up company at over 5 million USD? I shouldn't even have to answer that question. So a company that isn't making any money is now worth over 5 million. How long, if at all, do you think it will take for your stake to be worth anything? For it to double, the company, once it goes live, would have to make 5 million on top of that, and that's assuming 100% of their earnings will go into the value of Ether, which it certainly won't.

Just think about it and you'll see how overly-inflated the evaluation is.
