Fire Lotto presentation had big success in Zurich.
Instead of 10 min it was 25 with questions and answers and alot of applauses at the end. Also Fire Lotto received a proposal from one good exchange...
That is not a problem to burn investor's money to appear at many conferences and to do PR/marketing.
The more beautiful target would be to create whole project that will generate income (be self sustainable) and use that funds for marketing while investor's founds could be used only to scale-up (and generate passive income/dividends for investors).
Again I repeat: burn ICO's money is pretty easy task and that is how most of current businesses do.
