I'm curious about some publications mentioning that "only 2% of the addresses holds 1 Bitcoin or more".
I found this to be quite surprising, since I always supposed longtime hodlers to be the larger segment of the Bitcoin ecosystem and not just a small fraction.
How accurate this data could be?
The percentage of total addresses is pretty meaningless considering that there can be hundreds of millions of addresses created over time. Since there can only be 21 million bitcoins, this is the max amount of addresses that could potentially hold 1 btc. A more meaningful metric would be the percent of addresses that hold 1 btc of the max possible.
Although even then, what's the point of knowing this? I don't see any valuable insight it provides.
