We have noticed that a lot of successful ICOs have exhibited common factors. One of these is their use of hype. Another is a detailed presentation of the company's roadmap.
From what I understand, most successful ICOs are projects that have good communication with their communities. New projects that are informative and also have a roadmap and whitepaper that are realistic are more attractive to investors because the community needs information about the progress of the project being worked on
Investors are very important and presenting the potentials of the project to attract investors is the key to have a successful ICO's. The point of introducing your project with clear road plans and have a decency to keep updating the communities. It will bring prosperity and in the long process
more investors will follow the project and store the coin for much higher value.
In regards to hypes. It helps in the short run but nowadays investors is knowledgeable they will not follow unless they see the positive prospects.
