What do you mean by profitable? I've been running this node for 4 years. I don't try to do anything but run a node for my family. I don't sell channels either. I do use Lightning Terminal to auto balance fees for me. I don't do any management or babysitting any more. I haven't for the last 2 years. Ain't nobody got time for that!

Honestly, this is a question for @LNBϟG. Their whole business is running profitable nodes.

By profitable I do not mean running a business but just not losing sats by running it. There are costs in opening and rebalancing channels and you would need to be routing a sufficient number of transactions to cover these costs. But as you ended by saying "ain't no body got time for that" perhaps this is just a level of complexity I should not delve in to and I should just rely on a private channel to a LSP.
