No, the average person doesn't care if it's global, they don't care if it's decentralized. What the average person cares about is if it works to buy food and pay their bills. Now investors are quite a bit different beast and also well off global travelers.
Sure! But the world is getting close by the internet and social media. We were much more distant to each of us 10 years ago. i think day by day global, decentralized money become more important for the average person.
