Bitrad.io is one of the project i like the most. They stream radio stations and reward listeners giving them some BRO.
BRO is a PoS based criptocurrency, it also uses masternodes. But that is not what i want to share, yesterday i noticed that on the profile now there is an option to pay for a premium account. The premium gives 20% more reward while listening, and removes ads on the website. It only cost 0.1 BRO for 30 days.
I think it's pretty cheap right now, because i receive 0.1 BRO in 2 hours, just listening radio. Check it out: https://bitrad.io/
