Is there a website where I can view the wealth distribution of BTC and different altcoins?
I know such data are only estimates (address != holder, exchange wallets, etc.), but would still like to get a feeling of how different coins are distributed among its holders.
You can collect one by one information. But you can not find a list that is all together. Imagine, dozens of new projects are being created every day and you need to follow them all, or any shitcoin gains value, and while it actually does not have any value at all, it makes its owners wealthy. It is almost impossible to set up the system and always show the correct data.
