Hey mate, that's a solid question. You're right, spending Bitcoin is becoming easier by the day but earning it still needs some work.
To create a circular economy with Bitcoin we need to encourage businesses both big and small to start accepting it as payment for goods and services. This means educating them about the benefits of Bitcoin and making sure they have easy access to tools that allow them to accept it.
At the same time, we can't rely on just big corporations like Uber or Airbnb. We gotta support local businesses who are more open-minded and willing to innovate. If they start paying employees in Bitcoin, it'll help circulate coins within communities.
Lastly, we should promote platforms where users can earn sats for their skills or content - not just through donations but also via microtransactions for reviews, comments or other participatory actions.
Remember though - Rome wasn't built in a day! It's gonna take time but I believe if we keep pushing forward with these strategies then gradually more folks will get involved in this new economy.
