You mean hype ones? I can't even imagine who are those people believing they will have a long live and will blast again. Hype lives like that - it's a terminated process and in the exact moment owners of the coin and a number of luckies will get a great income and that's it. No one will work on its improvement further. It's easier to create another such coin and get some more extra money on its hype.
It seems to me that only a certain type of people is inclined to idealize hype coins. Yes, it is, because I believe that only people who tend to believe empty promises can take my word for it, especially if the project is relatively new and undeveloped.
