ZFR is the best inbound to buy as a merchant/service, but ensure fees on other channels are high enough to prevent draining it. I do not recommend purchasing ZFR as a router, tho can make sense in a bootstrapping sense
Purchasing LNBIG inbound is highly unreliable, they have at least a couple hundred BTC inbound shortage
Magma selling faces the largest addressable market, being implementation-agnostic and requiring no client. However they take a decent cut now (1000ppm unless you sub). Magma seems to have facilitated more volume in the last month than Liq Ads or Pool and is much much easier to use and sell with than others
Pool can garner the highest premium in my experience, and interfaces with the largest implementation, tho requires client and some know how. Voltage plugs into this to make it somewhat easier. Additionally, to use Pool well you need to layer a lot of liquidity at different rates / lease lengths
Not much experience with CLN liq ads, though addressable market is currently relatively tiny
appreciate the thoughtful response. how can you tell that lnbig has an inbound shortage?
also, you’re right that magma has deployed more by. than pool this month, but ln+ has deployed more btc this month than both combined.
ln+ has a different system of getting liquidity though, i believe most of their vol is through triangle or square “swaps” rather than direct purchase. does this matter for a routing node?

I was running some rudimentary probing thru LNbig a couple weeks back, no hard numbers but inbound shortage is v apparent. You can see this in the difficulty it can take in trying to rebalance lnbig channels
Yes I'd classify LN+ seperately, no actual buying/selling occurs there atm. Swaps are essentially "I'll open a channel to Bob if Alice opens a channel to me" -- it is not a very selective process and the 'quality' of peers highly varies, you basically open a chan to random peer and receive a random chan in return. Some swap peers are great, some are bad. Contrast that to Magma where you may be selective in your peer or to Pool which uses an internal scoring system
