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.
there is no such website available in the market now however if you want to check your personal portfolio and your personal wealth in the field you can save everything in a blockfolio application.
But there are some websites only shows the richest Bitcoin addresses kind of stoves but I am not sure how much that is truth.
