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 check other balances using their address but it hard to find a lot of bounty for now by using a simple website because of updating it always and everyday there are a lot of campaigns do made. There are several scammers and there are some token that are no value. You can check it's real value using its coinmarket cap. There are also have some website from bounty campaign which they create sometimes to know for others that there has a lot of investor and an organize plan.
