Yeah lets say you earn 1000ppm for routing 1mio from kraken to xyz. To rebalance Kraken its quite expensive so 80-90 percent costs is necessary for rebalancing. Some days are cheaper some are more expensive.

So lets say it cost you 800 sats to rebalance your profit is 200.

More channels you have more cheaper is rebalancing because your node finds way more routes through the network.

There are some good videos about the lndg basics from jonathan levi on youtube. But a lot was try and error. Once its setup its pretty cool and not that time expensive to run bigger nodes.

Plus there is a lndg telegram channel

But yeah let me know what you need to know and i will help you here as good as i can. So maybe other node runners could profit from that too.

Its hard to find a lot of infos for lndg on the www
