I think hype has died down in crypto world. it's not as strong as it was in 2017, where most newbies fell for the traps of hypes and lost money in the process. People are now wiser and tend to do more research before any investment move.
But the hype will always there, whatever you said but it's moving to the a new thing like from ICO to the IEO. Hype can be created by anything that related to the development of even instant listing on the major exchange site. It can't be erased from the world because people are still betting on the crypto.
