OPUS are my favorite.
They are most generous to the artist and are in a final phase to deliver a good working product.
I wonder why Opus still lacks the volume and liquidity. Judging from the community, the white paper and the website they are far superior compared to MusiCoin
I think because they are not properly communicating with users around.
They had the same problem during the ICO. And they were saved by their community manager juarez_12 or something like that who were very responsive in both ANN and Bounty. But they are the best music project around.
Opus changed own direction to streaming music from distributed storage on IPFS. I don't know why. I think they truly appreciated own forces and team and decided to some correction. I will watch for Opus. Other projects not interested for me
