This one is great! A real product for a blockchain based platform or cryptocurrency.

Pros:

• IOT integrated device. Controllable via gestures and voice.
• Another way for a musician to incentivize his/her talent and skills
• Uniquely made via cryptocurrency and blockchain

Cons:

• For a regular musician, it takes time to dig in with this kind of technology
• Firsthand confusion about the nature of incentivization
• Common structure and can be easily patented without the superb tech behind.
