Advertising is one of the important elements. But the community, of course, should help developers to promote the project in which it is interested.
You can promote using social networks, but not all social networks perceive such advertising projects, with this you need to be careful, Twitter does not accept ICO projects at all
Twitter and Facebook are actively opposing the promotion of ICO, although they are going to release their own cryptocurrency. And if everything is not clear with Twitter, Facebook has already officially announced the release of its cryptocurrency. So it is dishonest on their part.
But Twitter has recently blocked a lot of accounts related to cryptocurrency. And this news really upset me
