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?

Honestly, to date I still don't understand about the character of Lightning-Network, Is it Centralized or Decentralized? But I have heard, that Lightning-Network is very good to implement especially for transaction purposes. By utilizing Lightning-Network, reportedly can carry out transactions with the cost of ZERO (but whether or not it's true or not). And I also heard the bad news, that by utilizing the Lightning Network it was rumored that it could damage the bitcoin ecosystem (this too, I didn't know the truth).
