So I've done this for over a year on my own, no custody services. Providing liquidity of >10M sats. The result: set a fee of over 10 sats: no routing. Then I thought: set fees to 1 sat so I'll get routing. So I did. The result of that was that those that opened a channel with me instantly drained those channels and made my channels unballanced. It resulted in me being suspicious of sats laundering. After a while of me reballancing those channels, I had enough of it. All channels closed. For now, I won't be having channels anymore. I wanted to support the lightning network, but it only got me frustration and extra work. My goal wasn't even to earn sats in the first place. 😏
