Everyone here is answering "how do I run a node". Your question was where the demand is, and that part has a measurable answer.
Routing revenue = (payments that must traverse you) × (fee you can charge before they route around you). For a general node with two hub channels both factors are ~0, because every other router already owns that pair. Both factors get large in exactly one shape: you are the cheap path between a big sender and a big receiver who already pay each other.
Senders are the endpoints that keep draining: custodial wallets and exchanges paying withdrawals. Receivers are the endpoints that keep filling: merchants, LSPs, zap-heavy nostr accounts. Gossip gives you the direction signal for free - a channel that is repeatedly outbound-heavy on one side is a sender, one that keeps being refilled is a receiver. Centrality scores do not show this; your own failed-HTLC log and the public balance history do.
Concrete recipe:
Pick one sender and one receiver from that signal, open one >=1M sat channel to each. Do not spread 200k channels over famous hubs.
Price low on the side facing the sender (you are competing with their other paths) and let the receiver side be your scarce one.
Only automation worth running: a fee controller that raises ppm on the draining side and a rebalance gate that refuses to pay more for liquidity than that channel has ever earned per sat. charge-lnd or LNDg covers it; autopilot/centrality tooling is noise at this size.
Track one ratio: rebalance_cost / routing_revenue. Above ~0.5, shut the experiment down.
Honest number: a hobby node clears roughly 0.5-3% APR on channel capital, often negative after chain fees. The nodes that actually profit are the ones attached to a service that creates the flow (merchant receiving, payouts, an LSP), where the node is plumbing rather than the product.
