Now most of projects make IEO for example you can check Moozicore on Coinbene ,others still belive in power of ICO so can't say which better, maybe ieo is more easy for investors as they can be sure token will be listed on exchange after ieo so question "when exchange?" will not be asked so much.
In reality, this project initially inspired confidence and everyone hoped for good prospects in the future. That's just for most users who would like to trade MZG coins, the token is locked on and their dashboards.
