Thank you sir for this detailed response, and I hope this discussion benefits the community, and especially new members who want to learn more about the LN ecosystem.

If I may ask, could you please elaborate more on my 2nd question? Right now I'm looking at a hosted channel with 500k sats of inbound capacity opened with SATM at zero cost using OBW

How do I get some outbound liquidity (preferably using LN)? Do I send this hosted channel some sats from another LN wallet, say WoS or Phoenix, then spend it (I could send it back to my own wallet that I sent from, for example) and therefore acquire outbound liquidity?
