Most decentralized cryptocurrency?

[Abiky]

Every day, new cryptocurrencies emerge with specific features that aim to make the Blockchain industry a better place. Bitcoin has been a long proponent of decentralization, but it's not perfect. Being a PoW cryptocurrency, it's subject to mining pools where they control an enormous amount of the network's hashrate. On the other hand, PoS cryptocurrencies have the issue of making the rich richer over time. As for DPoS cryptocurrencies, they're largely controlled by big players in the industry (most often, delegates with a lot of money will vote for themselves).

This it makes me wonder which is the most decentralized cryptocurrency? After all, there's no such thing as 100% decentralization. But the more decentralized a cryptocurrency is, the better. What are your thoughts?
