the lightning fee market is still evolving, and imo it hasn’t fully played out yet. 

folks like @zerofeerouting could push other nodes to lower their routing fees to compete for a more central location on the network graph, while it’s also possible that fee rates rise over time to compensate node operators more for their liquidity.

Thanks for the detailed response! I get why the Bitcoin line will change horizontally. 

I'm a little confused as to why the lighting line will shift vertically. Why do you say that?

Payment Systems And Their Fees

thanks!

the credit card line is based off the standard 2.9% + $0.30 fee most major processors charge.

the bitcoin line is based on current mempool rates. the horizontal position of the bitcoin line will change as mempool fees go up or down, but the curve of the line will likely remain the same over time.

the vertical position of the lightning line will also change over time, but the line should remain flat, always enabling opportunities for making small value payments.
