It works well, but it’s not exactly passive. First you need big enough routes in place to catch this size HTLCs. And you have to be pretty proactive to get liquidity where it needs to be which is costly and time consuming as well. So catching a nice forward like this is great but it’s only part of the story!

do you actively rebalance or just let the sats flow?
I actively rebalance certain channels– The key to lightning is putting liquidity where it is needed in the network. Especially routes to/from exchanges can be high volume but in one direction only. If you don’t manually replenish them they won’t route.
