It's not so simple as there are several factors at play. So, let's say per the graph that ~88% of
all bitcoin addresses that were ever created that contained any amount of btc and currently contain less than .1btc currently are change addresses or even go so far as addresses containing "dust" amounts ( a term used for unspendable/insignificant amount of btc), so they are not counted as an individual bitcoin owner.
Now, we have a universe of addresses where you (falsely) assume are individually owned. How so? Because bitcoin is pseudo-anonymous and any address cannot be attributed to any person unless the person is careless or doesn't care, the address can be traced to him or her. In addition, a bitcoin owner can have not just one, but many addresses, and in fact is encouraged to have many wallets and many addresses per wallet.
I don't claim to know if the whales are still in-control of most of the bitcoins in existence, or if they have cashed out a portion, or some, or most of their holdings, at a price of $100, $1000, $10,000 per bitcoin. When bitcoin first hit $1,200 in 2013, many bitcoin enthusiasts quit their jobs and falsely thought they could live off their bitcoin holdings, only to be awaken to the 2 year bear market and had to go back to work and sell most of their bitcoins in order to survive as the bitcoin bottomed at $165 each.
What we do know, as bitcoin is a public ledger, is that Satoshi's bitcoins have not moved. If you wish to go down the rabbit hole, look into the concept of bitcoin days destroyed (not as bad as it sounds) which mathematically tries to explain the velocity (of money) or movement of bitcoin from address to address.
So there you have it, my attempt at trying to dispel the myth, but neither claiming it's the truth, but more of a logical argument. No one should be claiming to know unless they can prove it mathematically.
