#Bitcoin this is the most important power law. 
I love it because it spans over many orders of magnitude both in Addresses and in Price.

People say Addresses are not a good proxy for users. 
It is a direct measure from the block chain. It is a direct observable and it is a direct measure of activity. So contrary to other people that focus on "users" I rather focus on addresses because it is a more direct measure. It is interesting to speculate how many Bitcoiners are there but Addresses is what matters. Always think like a physicist, I care about what I can measure. 

Even if now a lot of value is in few addresses, because of the ETFs for example, that is ok because addresses with larger values have big impact on price but they grow slower so they all average out. 

I will go deeper in studying the addresses because there is a lot of info there but this graph is just amazing. 
Most informative of them all.
