One of my basis of a legit ICO is facebook. Why?
Because in facebook you can see if there's an update about their project; if the team is doing their job to promote their project. It is one of my basis, how about you what are your basis?
Share your thoughts.
This is incomplete basis of a legit ICOs, Legit ICOs have strong marketing and technical teams. It will be better to go through up every social media for updates like FB, twitter, reddit, LinkedIn, telegram and steemit. Also more importantly Bitcointalk forum ANN, check how they are responding to the question's.
