I think that luck does not exist, the more in a sphere such as cryptoeconomics. In order to enter a profitable project, you need to analyze all the risks, and then again analyze everything.
I think it exist because how can you explain those people who have joined in here just first time like for example my friend whom I thought of this for the first time and when he join his first campaign have received much more money than I do so thar means he is lucky in picking an ico because you cannot tell if an ico is gonna provide you a huge money or not.
