It's not surprising though, since one of the main purposes of Bitcoin is to provide privacy, so the number of unknown owners should be higher than those who are known. Many of these people are probably just individuals who haven't linked their wallets to any identifiable entities, so they remain unknown.

You can see every transaction on the blockchain but you cannot identify everyone, that is normal and just because they are unknown doesn't mean the owners are hiding something. That's what makes Bitcoin different from the traditional financial system, where transactions are generally private, while Bitcoin transactions are publicly transparent but the identities of the wallet owners are not necessarily known.

Just try to subtract the Satoshi Bitcoin and other unknown whales who invested in Bitcoin and are still holding it today, and you'll see that almost all 55% is made up of what I just mentioned.

Anyway, this doesn't cause panic because many individuals hold a much larger share of the market than even those we think are giant holders; eventually, the network is more secure and safer for everyone, both the whales and every other individual who has invested in Bitcoin and is still holding.

It's even alarming that it has reached that level since the 45%, although still a minority, includes institutions that are catching up, they are buying Bitcoin to potentially dominate the market in the future. What was once pseudonymous, I'm afraid we might not fully enjoy that privacy in the future if we are forced to use centralized systems to exchange our Bitcoin, governments are doing everything they can to make it operate more like a bank, and they are undermining the nature of decentralization with their centralized regulations.

I don't get the idea why they continue to monitor the influxes that are into this chain. With the holdings that are from the publicly disclosed companies and exchanges, they're normal to be heavily monitored.

But trying to figure and track the private individuals or holders of the remaining percentile that they have no idea with, they better leave it and only focus on the publicly displayed amounts from these companies.

That is happening and I'm afraid that there's no way to stop them. It's either they sanction the exchange that will not obey to their regulations or the exchange have to implement the rules to their users.

Yes at first I was surprised that the statistic is as high as 45% buy by examining that
its clear why its 45%, centralised exchanges and institutional financial incestors etc.

1.] This is why staying away from KYC platforms is essential, it gives us a fighting chance
     of not ending up in that chart, we stay GREY and trade if we have to without KYC.

2.] There is a strong argument which goes against what a lot of people say is essential
     to Bitcoins design/philosophy/survival - That is to HODL. HODL'ing means we prolong the
     length of time the institutions have to become more and more dominant.

I was actually thinking about this, and I'm glad someone brought it up. It's almost impossible to know the actual number of Bitcoin owners out there. Most of the data we can easily access comes from centralized platforms and institutions that identify their users. If you buy Bitcoin without going through a centralized platform that requires KYC, it becomes more difficult to link your identity to your Bitcoin addresses. This is one of the things I appreciate about Bitcoin, although it doesn't guarantee complete anonymity.
The whole idea behind Bitcoin was to give people more financial freedom and the ability to transact without depending on centralized authorities. Unfortunately, many people seem to care less about these principles today because they are more focused on making profits from Bitcoin than understanding what it was created to achieve

It's not being murky when that is the design. It was meant to be pseudo anonymous with transparent addresses but no identity attached to them. This graph shows the extent of institutional investments we have had and how much centralisation we have had with exchanges, ETFs and companies holding that amount.

If we even considered this to be a flaw, the oceans of fiat and other assets servicing globally is more difficult to trace. A huge chunk of cash is untracked, flowing into crime or government corruption

In my opinion, anonymity is a golden rule—after all, why should bitcoin holders be known? So that someone can try to hack them? I actually think 55% is a low figure; in any case, 100% anonymity doesn't exist, since transactions are public.

Isn't that a good thing? It means that Bitcoin still works as it should, as a pseudonymous system where users can have assets without having to reveal their real-world identities on the blockchain.
What's a bit concerning, though, is how Coinbase, Binance, BlackRock, and various other centralized entities are continuing to increase their influence. The figure might still be around 45% at the moment, but if their share continues to grow, it could eventually raise concerns about how much influence these entities have.
