What is your actual purpose in looking for this data? would you make an article about them. If it's true, that's good, but you have to remember that all data only displays the ownership address, for identical data it may be anonymous and besides that, you can search for it in several popular data analysis tools including CipherTrace, Chainalysis, and CoinMetrics and data from Catenaccio can be used as a reference too.
I know for sure OP will have a very unique purpose why he/she is demanding for this data. But if the purpose for it is so unquie that other can learn from it, it will be good if OP can write an article about it for other in the forum to learn.
I'm with you on this, because it'll be good if OP has a unique reason for requesting Bitcoin, rich list, except for showing the fact that we have supper rich investors in Bitcoin, I don't see any meaningful reason to have the list. The list does not have any impact in the supply and demand of Bitcoin, because the identify of the wallet owners are concealed. Anyways I'm glad that he's able to get what he wants, and let it be useful for him, he perhaps wants to keep the list as a motivation for him to aspire to be like them.
