Some say that the Lightning Network is centralized, but from my point of view, it's still a decentralized solution to scale Bitcoin as anyone would be able to run a Lightning node at will. The huge advantages that it provides for Bitcoin such as dirt-cheap fees, and instant transactions would be too hard to ignore to implement in the future.

However, if the Lightning Network turns out to become a centralized solution for Bitcoin (like many claims it will), then it would be doomed as only those with a lot of wealth and power would be able to participate in this ecosystem.

What are your thoughts about this? Is Lightning really centralized? Or Decentralized?
