This is true that Essentia postponed mainnet release for indefinite term (probably for 1st quarter of 2019, but this is not exactly).

I read this in telegram...
Seems now everyone dissappointed in this project which have only false promised. They promised top 5 exchange during ICO, now they postponed mainnet.. The team looks like very unprofessional

You read it, but who wrote it. Maybe it's just a throw.
I will wait for the official announcement from the team.
Hello there, you can check out the official announcement from the team here -
https://t.me/essentiaoneBe sure to check official sources if you need clarification as people are quick to call scam without any substantial evidence. People correlate market performance with high/low quality performance of the project teams, where as its more so reflective of community sentiment.
Thank you
