Yes I read it already. There is no comparison to other decentralized music blockchains in Opus white paper. That's why I question. The white paper always compare to legacy systems but not other blockchains. Opus team address Voise in this thread, but not Muse or Library. They didn't mention concept and technical detail that make them different from everyone else.

The most important is that the project already did something in addition to the white paper as many now. Definitely invest.

I think Opus like a platform pay to play and helps singer can earning money from Opus community. Although this idea we had saw from other altcoin on market as Musicoin, Voise, Muse ... but in currently, same idea between some projects very normal, important how about developing by the devs from this project?

Having already invested in Opus, I joined this forum just to participate in the Twitter & FB campaigns, haha.

Nowadays it is impossible to resist piracy because you can find any songs at many sources so if somebody wants to steal your music they will do it even if Opus has a strong security
