I wonder, how Lightning Network is classified. Is it a mixer or not? Because:
1. You can open a channel (a decentralized equivalent of putting coins into some mixer).
2. You can send your coins inside LN (this is where "mixing" phase can happen).
3. You can close a channel, or even get your coins back, without closing your channel (because of swaps, and you can end up with different on-chain coins than you started with).
And then, the question is: if you have some LN wallet, that allows you to get your on-chain coins, without closing your channel, and that is the default behavior of this wallet (for example Phoenix wallet did that), then is it a mixer or not?
