I think the real challenge is to get people to spend it. I can see Lightning payments replacing cc’s.
From the stand point of just buying vs selling a good or service, i would argue that it’s marginally cheaper than buying since you’re getting the gross profit as a markup. For instance, I’m swapping a $50 (cost) lamp that is sold for $100 in Bitcoin. Yes there’s a tax cost to account for but it should still be better if you can get people to spend their Bitcoin.
Good conversations, maybe someone reads and gets inspired. 🤝
