In the last 4 months I paid a total of around ~0.22 BTC for roughly 600 channel opening/closing transactions even though my opening tx are always only paying a maximum of 1-5 sat/b and only maybe 75% of those channels were opened by myself. Pretty much all of those tx happened during times of insignificant network congestion. As soon as congestion goes up, things will get much worse and 0.22 BTC is already pretty bad!

If possible, this would be the best imho:

• manual fee setting whenever humanly possible (the algos just suck big time)
• stop overpaying (sometimes by more than 400% according to blockstream.info)
• use a standard target of 144 blocks instead of 2
• an option to manually adjust this target via config
• make it simple to get stuck TXs unstuck via CFP
• use less TXs, but that's already in the works: Deterministic channel keypath #1026
• get rid of unnecessary force closures (mostly an LND issue, afaik)
• option to combine closing and opening TXs
• option to open (and close) multiple channels with a single TX

Hopefully at least some of it can be implemented before the bull market starts picking up steam. Otherwise I fear that operating a routing node will become VERY expensive. I'm already paying hundreds of dollars each month...
