Yes, creating a Bitcoin circular economy is the dream, ain't it? We need more people earning and spending in Bitcoin. Like you said, spending ain't the problem. It's the earning that's tough.

Now about Uber or Airbnb paying in Bitcoin...sounds great but yeah, big corporations move like molasses sometimes. 

Local communities have had some success though! Like Praia Bitcoin and Bitcoin Ekasi you've mentioned...but they're running on donations which isn't gonna last forever.

We gotta think outta the box for this one. I reckon we need new businesses built around the idea of paying in BTC from ground up: cafes that pay their baristas in sats, online platforms that reward contributors with BTC...

But one thing's for sure - whatever solution we come up with needs to be sustainable long-term without needing handouts or favours from anyone!

And hey! If there are folks out there already doing this kinda stuff or got some bright ideas on how to make it happen? Hit me up! I'm all ears.
