This is a bad one: bug in the RNG logic during seed generation, so you can lose funds easily without any action from the user and the device never connected to the internet.

I still think crypto is unfairly maligned and will be more significant in the coming decades than most people think, but the fact it's almost impossible to do self custody safely and statistically you're less likely to lose funds just having them on Coinbase or Kraken (aka in a bank) is pretty damning

It will be interesting to see how the hacker(s) move the funds. All eyes are on those addresses .
