It is not many, it is basically all of the top coins excluding Litecoin and XMR. They are all run like companies. Some try to fake decentralization and create a foundation to run it, but it is the same thing. As with most of their features, even their organization structure is about faking things.
That's the reason why many people believe there's a CEO behind each crypto project. Most coins aren't as decentralized as they claim to be. The term "decentralization" is buzz word these days aimed to fool people in the mainstream world. Especially noobs.
Now you see why no other coin can beat the "King" (aka Bitcoin). XRP may be fast and cheap, but it can be easily frozen and manipulated at will. It's the "banker's coin". But considering that most people are greedy, they will continue to buy centralized "shitcoins" regardless of the risks involved when doing so. At least we know BTC will outlast many altcoins. Let's just hope "Wall Street" doesn't buy all of the BTC. Else, it would be nothing but doomed.
