I thought the funds raised from these ICOs are for the development of the project? what project are you talking to? i pitty those people who invested to your project and it seems their money will be wasted for nothing,getting millions of dollars will give you a lot of headaches especially when those investors started to dump your tokens,and those people will try to blame your ass because the price would fall below the ICO price.
And for developing a project you will need fiat currency. At least in my country I have to pay office rent, salaries, expenses, ... in fiat. So in order to develop a project a realistic amount of the ICO money needs to be exchanged.
