I'll put it this way: Lightning is developed by some very clever developers BUT they still call the core software a "beta" version.
Whilst I don't see a catastrophic loss happening, there are known issues within the system which can cost me a lot of sats if communications errors happen at a time of high Bitcoin fees.
I'm running the service, and I am taking a certain amount of considered risk, but I don't want to be holding a lot of sats in trust for others. This really is a stepping stone to @vsc.network which will de-risk this for me.
