One day, I'll be able to buy daily groceries on OpenBazaar using Lightning Network.
Looks like the first step has been taken at Farmer's Market, University District, Seattle right now...

Another step has been taken at Spar Supermarket in Arnhem city, Netherlands. You can buy groceries and pay in Bitcoin over Lightning Network...

This just proves that bitcoin is already taking over on some places little by little. We all know that someday, each and everyone in the world will be using crypto as a mode of payment and this right here shows us how is that happening. It will be a huge convenient for many people as our vision comes to life.
