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?

You could maybe argue that some decentralisation may have been sacrificed in order to scale but I think it still maintains enough decentralisation to remain relevant and survive. As a second layer solution I think it is the best we can come up with at the moment and I can see a future where you will need as little as a smart phone to run a lightning node, in a few years of course so over time it will become allot more decentralised. Like any protocol I suppose
