opus is going in the right way slow and steady wins race
soon opus will be huge in the crypto market
this is great ''The UX is currently in the intensive creation phase, and we are starting to have a clearer idea of what the final player will look like from the user’s perspective.''

I have invested in the ICO, recently I bought more opus token and I believe in this project. Keep going guys with your work, I hope be be rich thanks to this investment.

We have been waiting so long to get technical updates. I hope all the legal issues have been resolved and we can focus on development and new marketing strategies.

well we hope so. because a lot of us may noticed it that despite that they have more artist already or even if we see a small improvement, the price still knocked out in 100-200 sats. 

Be patient guys. This is a good team with a good product. We don't want pumps, we can steady growth. Use movements from 1-2cents to accumulate.

yes me too waiting for some technical updates but right now i think team is enjoying holidays
and maybe after holidays some good news will be release by the opus team
opus project is ready to explode in the market.
now opus team should be on to the marketing strategies and make some good move to list opus coin on good exchange

I remember this project, could not invest but seemed quite good, ill take some time to catch up and eventually buy some token 

much awaited breakout

Indeed, a simple act can change a thing.

Since they have the question and answer portion,  am now starting to gain confidence about opus. Hope this will continue and kicks of by 2018.
