Nifty has a great summary of the recent btc++ privacy edition in Riga. Lots of links and some great context for each of the people/projects she highlights.
I watched the coinjoin talks first. I like these because solutions are here already; it's not some PoC anymore.
I enjoyed @kruw's talk. Not sure about the not-degrading-over-time; maybe we should have a discussion here on SN about that some time.
I also found it rather amusing that @petertodd at the end of his coinjoin analysis describes literally how I pay the ~AI territory fees and do most my personal spending: on-chain payment -> wasabi -> open new LN channel -> spend through LN.
when you close the channel, what do you do with the 1% or so remaining? I personally like to donate it to charities.
Until now, I've just re-mixed it into hot wallet. Donation is actually a great idea. The more joined coins in circulation, the better.
I also don't close all of them - having some inbound liquidity can be useful in case someone wants to send some sats over LN. This way I don't need any LSP; I'm basically providing my own inbound this way.
Also, do you make a new node each time?
Yes, new node, otherwise you kinda just re-join the utxos. I currently like Blixt for this. Since 3 months I started using it for this and it's super easy to just close a channel and remove the entire thing, restart from scratch. The only downside is that I've had some private channels that were rather sensitive to routing issues on Blixt though; I need to look into that.
