The smallest you can open I think is around 150k, at least from the predefined in Alby Hub. Yesterday I opened an extra one with 500k because I wanted redundancy and a connection within Europe to have faster connection time to me. You can browse a lightning map and see which big nodes are around you and then copy their public key. What I did was to find a few, put their public key in Alby Hub and try to open a very small channel like 50k sats. Then the channel either opens or fails mentioning the minimum size they accept.

Thanx! This is helpful, I’m trying to get my hands dirty but also still a bit hesitant because I don’t fully understand it all yet 😊🙈
The first step is the difficult one, just try on an old laptop or pc if you have one laying around 😉
I already got that up and running. Tried it first on an old laptop like you mentioned, had power and battery issues all the time. I run a bitcoin node on an Umbrel home now. It’s just the cost of the channel size, or forced closures I’ve read about that ik worried about…
Ah nice! Well the cost is essentially the cost of you sending a transaction on-chain. If the fees are low then the cost is ok... But that is essentially going to be a channel for spending sats. Then you need a channel to receive as well, OR send half of the sats on that channel to a lightning wallet like Strike or similar and the the channel will be balanced and have space to receive as well.
Ok, I’ve sort of understood that indeed. Nice to have it explained again 👍 And do you run them publicly or privately?
