So... if each wallet holding 1 bitcoin belonged to a different person (hint: they don't) that would be roughly .0125% of the global population (assuming 8 billion people).

In reality, some people with more than 1 bitcoin will have several wallets with more than 1 in each. So, the real percentage is even smaller.

By contrast, there are approximately 58 million millionaires in US dollar terms. That's about .7% of people.

I'd be curious to know how many of the world's current millionaires own an address with 1 or more bitcoin.
