Worldwide? Really?

4.5m adresses with 0.1 to 1

800k adresses with 1 to 10

140k adresses with 10 to 100

People control 10 adresses let’s say so above numbers don’t mean that many people have 1 but also some of the 4.5m between 0.1 to 1 maybe belong to people that have 1 all in

My best guess would be around 300k people

About 1 million addresses have more than 1 BTC. Take away corporations and such and multiple wallets per person.. so maybe

Agreed. That's the higher end of the range.
