If you are providing marketing services for crypto projects, let me know about them. We are preparing to launch an ICO project and we would like to consider all available options to get our project seen by as many crypto people as possible.
The one of the best way to promote ICO is starting Bounty campaign, I would like to suggest you hire yahoo, Sergei.Gerasimenko or to get a better result.
Secondly, you can use google adword (or google ads) to promote your ICO.
Thirdly contact different site/blog owners to promote your ICO. And Ask ICO Listing sites to list your ICO.
