I understand that this would be bad news for other holders of bitcoin, but really when it comes to cryptocurrencies we have lots of choice.  The alleged bitcoin thieves know that if they dump their holdings or otherwise misuse the stolen loot they can destroy the value of bitcoin before they can fully cash out.  They also know we have many other currencies that users could switch to.  Bitcoin has the first mover advantage, brand name, and the fact that people have for whatever reason piled massive amounts of money in to it.  But that's it.  Bitcoin doesn't do anything unique that dozens of other cryptocurrencies.
