Hello everyone!
I was thinking about one thing, Satoshi once said:
"In a few decades when the reward gets too small, the transaction fee will become the main compensation for [mining] nodes. I’m sure that in 20 years there will either be very large transaction volume or no volume."

As far as I know, in Lightning Network transactions, miners are not paid. So, doesn't this thing affect Bitcoin Network? If miners don't get enough fees to have a decent profit, they will be likely to stop mining.

Can someone explain this situation?
