The top 1000 coin holders own 50% of the coins.
you are just giving a random number out of thin air without even thinking about it!
first of all you can not count how many people own how much bitcoin. it can be 10 person holding 10 million bitcoin or it can be 10 million people holding 10 bitcoin each.
all you can see is the addresses and their balances. and according to stats 4,424,141 BTC is among 134,219 addresses each owning 10 to 100 bitcoin. 1,461,212 BTC is among 549,350 addresses and so on.
also you have to consider addresses like exchange cold storages that are holding 100,000-200,000
BTC which belongs to millions of users not the exchange itself.
Think about that and then tell me if that it can't be centralized...
being decentralized doesn't mean everyone should have the same amount of bitcoin at this point. it actually has nothing to do with how much bitcoin different people have.
besides, nobody was preventing you to mine bitcoin back in 2009-2013 with your PC and earn 10,000 bitcoin in a short time.
nobody was preventing you to buy bitcoin when it was like $0.1.
i bought a lot of bitcoin back when it was $200, a lot of people bought it when it was $1000 this year. and a lot more are buying it when it is $16,000 now and soon in a couple of years someone will cry about that too!
Chinese and/or East European Miners are in a great position to for a cartel using their holding and future production of BTC, to manipluated exchanges and influence Futures trading.
Central Banks create fiat from thin air and have investment banks buy up BTC.
again you have no proof of this. you are just making a random guess.
With controlling interests they could fork the hell out off btc, they could crash it in favor of a coin more suited to their liking. Influnce laws to criminalize crypto. The list of nightmare scenarios is significant and no one is talking about the
now i am convinced you are trying to spread FUD.
forks have been happening from day 1. there are currently near 700 forks of bitcoin available.
