Thanks for all the answers, but the core point was NOT answered or disproved.
That is a fact. So today, there are 225.000 bitcoin adresses today that have more than 0 BTC balance and as you all mentioned, that a user has more than one adress, the number of users is somewhere near 40.000 users.
A lot of answers in the thread have been:
- A user has more than one adress
- Lots of users use cold storage
I totally agree with you. But that even underlines my argument. My assumption is, that a user has one or more exclusive bitcoin adresses. I see no case, that users would share an adress. I assume that each blockchain.info wallet is associated with at least one unique adress.
My definition of a user is a hodler. A person that holds bitcoin at the moment. And that maximum is 225.000 persons today.
If I assume that a user has on average 5 adresses, than there are round about 40.000 people that hold bitcoin.
The only argument that I could see, is that wallet services like blockchain.info use shared adresses. But I just checked and can confirm that I have a unique adress.
Looking forward to your feedback!
