Let’s look at BNB, I consider it to be very centralised, it is regulated by Binance. But I think that the most centralised currencies are collateralized stablecoins like Tether. They are totally dependent on their collateral, and sequentially, on the company they were emissioned by.
BNB is extremely centralized. But stablecoins are worse. I've seen many times where both Tether and USD Coin's respective issuers froze users' funds at will. They've essentially "blacklisted" certain ETH addresses because transactions were deemed suspicious. This tells us that using stablecoins is no different than using an ordinary bank account.
Most people are miseducated about crypto/Blockchain tech, so they're made to believe that everything is decentralized, when in fact, it's not. As long as the majority has this mindset, centralized cryptocurrencies will only grow bigger over time. There's no need to worry about a few cryptocurrencies becoming centralized as long as there's one decentralized alternative on the market. Bitcoin may be all you need to obtain true financial freedom thanks to its decentralized and censorship-resistant design. I hope it stays that way forever so that Satoshi's vision could be fulfilled. Just my opinion
