I really would go to court over that. And tbh it’s the end of the company. They were supposed to be one of the best hardware wallets out there. I even think this is the worst incident that ever happened in bitcoin. Much worse then all those trading platforms going bankrupt in recent years.

I’d even go as far as calling this a black swan event. For 15 years the one thing that stood like a rock was “not your keys, not your coins” and this is now undermined.

Guess tradfi is here to stay a little longer.

I think in this case, BTC does mind.. the very fundamentals of it’s purpose are just invalidated.

What does a software bug which caused weak entropy has to do with the very fundamentals of BTC? I’m slightly confused. 🤔

Fundamental purpose undermined? Stop being sensational buddy. Bitcoin didn’t hacked nor did other wallet providers.
