CoinJoin Privacy Failures and Undoing Anonymity

Bitcoin HORROR Stories with BTC Sessions: Mistakes That Cost Everything In Part 2 of our conversation, Ben Perrin, @BTCsessions ,opens up like never before, sharing real-world Bitcoin disasters, OPSEC failures, privacy traps, and security mistakes you do not want to repeat.

From cold storage setups that weren’t so cold, to the emotional toll of burnout, scams, social engineering attacks, and multisig misunderstandings. This episode is a must-watch for anyone serious about self-custody, sovereignty, and survival in the age of surveillance.

We cover:

• The dangers of weak OPSEC (and what he does instead)

• Mistakes people make after watching tutorials

• Why multi-sig isn’t magic and what your family needs to know

• Privacy fails in CoinJoin and Lightning

• Fee nightmares, inheritance setups, and physical threats

• What to avoid at conferences & how to stay safe

• Lessons from the hardest Bitcoin horror stories

If you’ve ever said “I’ll deal with that later,” this episode is for you.
