It would be enough to make only one of those factors to fail the project. Even solid team members are making mistakes, but the biggest problem is greed, because they are making discounts to collect more money and are not willing to pay huge fees for a good listing.
Greed is inevitable, but this is different matter when the team would offer huge token discounts - up to 50% which is more often causes the token price to plunge right away after being listed on an exchange because of discounted investors gladly dumping their big discounted stash!
To this effect, I've have never seen yet any project that gives huge discounts during its ICO that has never suffered a drastic plunge in its token price and effectively affecting its financial funds needed for development to continue. I would say this is the result of poor marketing plan and ultimately, a product of poor financial planning.!
