Fact check: true.

Also, efficiency does matter. It's not good if you need to do 1000's of coinjoins to get reasonable privacy. Block size is limited.

Yes, the issue is not symmetric. But the economics just don't make sense: the person paying for privacy isn't getting it, and the people getting paid for that service are.

...at which point you really gotta ask why don't you just use Wasabi, which can get a better and more reliable k-anonymity set per transaction? JoinMarket should fix this issue too, maybe with some kind of out-of-band payment scheme. But even if it doesn't seems thwt Wasabi's huge transaction model is more efficient.

https://petertodd.org/2025/coinjoin-comparison My comparison of the three major forms of coinjoin in active use: Wasabi, JoinMarket, and Payjoin. tl;dr: Payjoin is cool and you should use it if possible. JoinMarket unfortunately has a serious flaw. Wasabi is the best overall and provides decent privacy.

...and yet again this morning: I actually heard that particular attack – and indirectly saw it reflected off a nearby building. An extremely loud attack even though I was multiple kilometers away from it.

Russians were particularly psychopathic this morning. After a long air raid with hundreds of drones they stopped. People went back home to their apartments at 3:28am. At 4:30am, with everyone asleep, they launched a set of fast moving missiles at an apartment building to try to kill as many Ukrainians as possible – unlike the cheaper drones, missiles can get to Kyiv in just a few minutes. So far there's 11 confirmed dead, including one 6 year old child from that building. Russian culture is just evil, and needs to be exterminated.

Celebrating the deaths of evil people doing evil things is not radical or unjustified in any way. It's perfectly normal, and healthy. Any reasonable person should be able to figure out good-vs-evil in this conflict.

Cheering on Ukrainians killing Russians isn't "cheer-leading for a tragic war". It's cheering for victory over evil. As for "having no part in it", I'm literally in Kyiv right now, for good reasons. Among them being there's a big Bitcoin community in Ukraine and this trip I did two panels at Bitcoin events. You're ultimately just trying to make excuses to let evil go unpunished. Evil that if not stopped in Ukraine, will certainly continue to spread. Russia has been invading neighbors for centuries. As a Canadian I'm well aware of the fact that Russia and Canada share a long northern border, and Russia has been challenging Canadian sovereignty in the north.

Given how quickly Ukraine was able to take territory in Kursk, it wouldn't be surprisingly if they were able repeat something like that again with a stockpile of saved up equipment. There's also evidence that Ukraine is scaling up their own Ukrainian produced ballistic missiles. A new push might also involve a bunch of Russian targets getting unexpectedly taken out.

Making this stop requires killing Russians, and lots of them.

Generally speaking they don't.

Two particularly impressive Ukrainian operations I found videos of lately. A very nicely done FPV ambush against a group of Russian soldiers: ...and an attack against a Russian fuel train – allegedly with long range drones – timed just right to destroy it in the middle of the central train station in Salsk, Russia: Obviously, taking out the train station as well is a great use of all that fuel; 380km from the front line.
