Dior had no faith in the French police to protect their store so they brought in their own security team to protect the flagship store in Paris tonight

1/ How I infiltrated a Chinese organized crime syndicate that has laundered $1B+ across multiple exploits for Lazarus Group. Posing as a client, I gathered intel that helped action freezes for the Feb 2025 Bybit exploit and attribute illicit activity onchain.

Stroke of a Pen I told Opus 5.5 to read my Bitcoin & monetary-history wikis & make a music video with code only. it used ElevenLabs for the track. Then a swarm of agents storyboarded and coded a 3:23 portrait reel. ~75 shots cut on the beats. Had to do 2 revisions - first the people looked like poorly animated stick figures & it rewrote the rigs. Then I said use matrix code to make it more interesting. Impressive!

We test the recovery too. Check the video here: youtube.com/watch?v=CMgQOvH5…

This Dropbox breach is going to result in lost funds. It's why you never save pictures or files of your seed phrases and private keys in the cloud (or a device synced to the cloud).
One reason I suspect the Dropbox breach may be massive is because I didn't get a login email notification when my account was accessed. Turns out, unlike every other login notification I've received from them, it went to spam. Likely due to a large uptick in their send volume...

Two footguns most bitcoiners miss when setting up multisig according to @lopp. Not backing up your wallet descriptor, and treating multi-vendor multisig as "set it and forget it.”
