From your link:

    In March 2023, the New York Times identified a list of
    just 34 Bitcoin mining facilities (controlled by 22
    different entities) in the United States, which
    represented about a third of the total worldwide
    Bitcoin mining network at the time.

34 such $365M/year entities would have to collude to attack bitcoin. And accept that their business is severely damaged afterwards.

So much for the decentralization and security of Bitcoin.

How does the situation look like in other chains?
