I only opened 2 large channels so far, and did not lose any sats to rebalancing. Made about 1000 sats from routing a 1 million sats transaction. Have 2+ million in outbound, 8 million in inbound. Spent 10000 sats opening channels. Not bad. I would recommend it, personally. It's definitely worth it.

Now, if you wants to have a "routing node" with dozens of channels, then you might end up losing sats from rebalancing. I don't need that. I just need inbound, outbound, large channels.
