However, thou Bitcoin transaction is transparent and can be seen by anyone on its blockchain, I doubt if it is possible to see a hierarchy of users with the highest amount of Bitcoin, as a criterion for you to have come up with this statement of yours.

This doesn't show users but addresses.
Some people own multiple rich addresses, some big rich addresses include multiple people (exchanges).
There's still nothing in this thread that would support OP's statement.
To take your point even further. If I look at one of my own wallets I can see around 50 or so receiving addresses, each one containing a small amount of btc, which represents a small amount of bitcoin I received in some past transaction. Therefore, my wallet alone represents about 50 data points, spread out, in that Bitcoin Rich List.
I do follow the data within the Bitcoin Rich List, just to see how bitcoin is moving about. But to form any real conclusions with what is happening with the rich list, it would require further research, and correlations with other types of bitcoin's data.
