I think he believes that all of CEX delisted it at that time but Monero is still listed on CEX like Mexc.
We can not blame those who believe that the ColdCard hack was an insider job because the security flaw was discovered years ago and the ColdCard team did nothing about it.
As a result, people will likely assume that it was a planned attack because no rational person would do that.
The actual red flag was the ColdCard CTO made an anonymous account in Github and started talking to himself through his real account. Why would he do that if there wasn't any deception, and if there wasn't any nefarious motivation.
Which also makes me think about Luke Dash Jr. - Something nefarious is also being hypothesized in BIP-100/FilterBoiCoin. People are starting to say Luke Dash Jr. is a bad actor.
Luke Jr. is always viewed as a mixed bag, and occasionally he will say something that gives the appearance that he is living in a different world.
I read that the ColdCard CTO is the author of the "libngu library that generated the weak seeds of Coinkite based on GPG signatures from his personal key on commits made under both names, but I dont know he pulled such a stunt on GitHub.
