We can endlessly discuss about ICO's and how they can be dangerous and scummy but still there will always be people who like this kind of gamble, and those who will claims they earned millions this way. Not so long ago whales were main sponsors and organizers of those events. How did they accomplished this? Easy they ware buying their own coins to achieve better price on exchanges. When trade starts they they manipulating price with sell walls and selling their own coins. How many times you asked yourself who sells under the ICO price, who is so stupid to do this? Invest few BTC's in marketing, start good campaign..
