Keep in mind an important aspect of these LN explorers: represent ONLY the public nodes/channels. There are mord other private (unannounced) nodes/channels.

Also please read my explanation here https://darth-coin.github.io/general/omg-ln-nodes-on-amazon-en.html And https://darth-coin.github.io/nodes/private-ln-nodes-en.html

So don't take those stats as real representative of LN, there's much more that we do not see it.
