centralised coins are quite common,

its same with ethereum (vitalik)

or ripple (garvin)

the true scam comes from the cryptocurrency index system that defines "shitcoins" and "nonshitcoins"

this distinguishinsation will weaken in time

correct.
without delving too deep into it I would love to know how much
bitcoin the top 10 exchanges "manage". Why not count the top
20 exchanges.

What about those people who believed in Bitcoin in the early days
and were able to mine a lot of coins and had the forsight to hold
on to them, to be able to see the future potential, I'm sure there
are quite a few of those people still with us and can potentially
be somewhere in that 1000 addresses....

Anyway if I am in this fictitious 15% I say thank you, Im glad to
be part of it.

I dont see a problem

world will not take the bitcoincultists and their attention hack serious for long,

its just a temporary condition that is currently being corect,

you misinterpret that for profit reasons and call it falsely a "bearmarket"

mark my words i am telling this since more than a year.

Probably less than a thousand people with a thousand private keys own 85% of the bitcoins.  Remember, if its in an exchange, you don't own it.  You are trusting them.

Also, that would imply 85% is being used as investments and only 15% is Available to spend.

We should start a new 1%  movement.

I think about the same thing happens in the current situation in the world. 85% of all wealth in the world belongs to 5% of the world's population. But you do not call fiat money a scam? Just the way the world works. The rich get richer, the poor get poorer. This is called capitalism. And as far as I know, mankind has not yet invented anything better. It is unlikely that cryptocurrencies will fundamentally change the current distribution structure of wealth in the world and even in individual countries. Well, except in very poor countries.

You will have to look at the storage history of those addresses to see how many of those addresses are owned by early adopters and how many of them have recently been used. Satoshi's addresses have a combined total of over 1 000 000 bitcoins and most large Bitcoin services store their bitcoins in cold storage in one or two addresses. <Exchanges Gambling sites Payment processors etc.>

One address might contain several thousand Bitcoin owners bitcoins that are stored in cold storage.

You can say the same thing about every currency to have ever existed.  Eight people own more than the entire bottom half of the population.  Whether it is USD, Euro, gold, or crypto the majority of the supply will end up in the hands of the few that own capital that creates the actual wealth.

This is true about exchanges, but the exchange addresses are just a few and like you said, these addresses refer to thousands of customers. So if we exclude a dozen addresses (or twenty), we are left with, let's say, 990/980 addresses.

It could also be that, apart from the dozen or so addresses related to Exchanges, the other 990 don't belong to 990 different people, but maybe much less. There could also be some big whale who owns maybe 10 or 20 of the biggest addresses that we see in the first thousand. We don't know in reality, because every address is of course anonymous. Maybe (just a supposition) one hundred real people own the majority of bitcoins in the first thousand addresses, apart from the exchange ones.

Here a look of the bitcoin rich list address, where is pointed out the addresses which are owned by exchanges:

https://bitinfocharts.com/top-100-richest-bitcoin-addresses.html

just agree with this , the 1 address from that 1000 can be from a company that investing on bitcoin or something like that
too early to judge if 1000 adress hold 85% and bitcoin was a scam

This info makes a lot of people suprised and horrified but it shouldn't. Even though 1k addresses doesn't mean 1k people, this figure shows how much bitcoin is opened to manipulation and speculation. We can see the same thing on fiat currencies. Most of US dollars is only in a few hands and they control almost entire exchanges.
