I'd like to point out that preventing things like this is literally this guy's day job. (Look him up) And he didn't know about SIM attacks. And he kept $100k

I'd like to point out that preventing things like this is literally this guy's day job. (Look him up) And he didn't know about SIM attacks. And he kept $100k of irreversibly transactible "money" on an exchange, despite their history of being hacked. This is what happens when you get involved with organized crime (which I consider Bitcoin to be): you become a victim. His lessons learned is of course not that reversible transactions is something good, not a "mistake" in the fiat banking system.
