Audius is a new music streaming protocol that allows artists to directly connect with their fans and get paid for their work. The project is still in its early stages, but the team has already built a working product and has secured partnerships with some of the biggest names in the music industry, including Warner Music Group.
Coinbase, one of the leading cryptocurrency exchanges, has not yet listed Audius. This is likely because Audius is still a very new project and Coinbase generally lists more established cryptocurrencies.
However, this could change in the future as Audius grows in popularity.
For now, if you want to buy Audius, you will need to use another exchange. Binance is currently the most popular exchange for trading Audius.
