Nice tutorial! wow 1h long... you dedicated a lot of time to this.
It's an interesting concept with levels of trust and increasing the amount on each step. I would avoid by any means the use of Liquid. Is complicating too much the UI, especially for a noob. For me was easy to understand all those swaps and shit, but I found them unnecessary, or at least to give more options of choice to the user:
  • where to receive (ecash, liquid, LN channel)
  • from which balance to spend
The on-the-fly opening channel with LSP is nice, I wonder what happen when you open the 2nd channel. Will be with the same LSP or another one, for more reliance?
