I wonder is there any difference?
Do they cause more confidence and grow rapidly in price? Or no difference?
Please share your knowledge or opinion.
Are you trying to compare the 100% Airdropped tokens and ICO funded projects?
If that is what you meant, then here is what I think:
They appear to have a similar pattern (many will pop up and many will soon die or fail) but the mortality rate of ICOs are a bit lower compared to airdrops. Although I can say that I have seen some notable 100% airdropped projects I joined that are performing better than ICOs but atleast 90% of them are gone now.
