From what I've heard running a LN node isn't something you do for a profit, but for the sake of helping the network; it often comes with costs one has to pay upfront and isn't likely to get back through routing fees, correct me if I'm wrong.

  • Also, there's problems with channels being forced to close, I'd rather stay away from LN.

What's the deal with JoinMarket though, any dangers or opportunities I'd have to be wary of?
