Guys you have nothing to worry. Essentia is actually really transparent and keeps sending weekly and monthly updates. The token problem is not a problem, every ico does this because they must maintain privacy of its stakeholders (and believe me, the stakeholders want to see the project succeed as much as you do). Also, the team members are real...
The problem with crypto investing is simple; there are too many people without experience in this field, therefore many people like to call things a scam too fast.

Just hold onto your tokens! Utility will be added. I've tried the app myself and it works great, just needs some minor improvements. When you bought these tokens, I hope you did it with a clear mind. There can be bumps along the road, but if the project is a success and adoption occurs, the value will increase. Just look at the feedback from community members in the telegram; most are really positive about the project and are actually using the product in various ways.

Instead of calling the project a scam, I highly recommend testing the app and give appropriate feedback etc... if you want your investment to moon, you can start by helping making the product a great one yourself (by being an unofficial ambassador). All little things help. It's too easy to fall for FUD, please educate yourselves guys.
