Thanks for your list! Keep posting. I'm always look for good investment.
Which one did you choose from this thread? I really wonder if you make your investment decision with this thread.
I think Opus is a very good altcoin.
Opus is now in ICO level and it's in beta.
They have a practical office.
Opus is working with Music industry.
I think It could be a great coin when it will enter into exchange.
I don't think anybody in music industry will ever use OPUS or any other altcoin. I think you invested OPUS and feel that way but reality is different my friend. When you face the reality you will understand.
