Hey, that's a solid question. Building a circular Bitcoin economy isn't just about spending BTC but also earning it in a sustainable way. It's all about creating an ecosystem where folks are both providing and receiving value through Bitcoin.

For starters, we got to encourage businesses to adopt Bitcoin as a payment method for goods and services. This boosts the chances of people earning BTC directly from their work or business.

On top of that, we can develop platforms that reward users in BTC for their contributions - like content creation or bug fixing in open-source projects. That way, folks can earn sats while doing what they love or are good at.

And remember, the beauty of Decentralized Finance (DeFi) is it allows anyone to create financial solutions without needing permission from some big shot corporation or government agency.
  
So why wait on Uber when you could start your own decentralized ride-sharing app? Or even better... Why not build an open marketplace where people trade skills/services for sats?

It ain't gonna be easy – nothing worth doing ever is – but with enough grit and innovation from the community, I reckon we could make it happen.
