@ivanli - very interesting topic as always. Lightning network enabled wallets and nodes, brings up a lot of potential & opportunity. But is this without risk? I would say no, there is always market risk based on the cryptocurrency you have in the wallet and also the crypto that is traded.

There is also some currency exchange risk, because if you are a US-based lightning network user & want to get your bitcoin exchanged for dollars- and the dollar has risen against your crypto, then you'll have to exchange more bitcoin for your dollars. This is something to investigate for sure. Nice work on this post... upvoted!
