I read about a cryptocurrency hack recently where they were able to steal tens of millions of dollars.
With that kind of money involved, I'm surprised this doesn't happen often.
Where you got the news from? Hacked wallets of individuals are way more common, but the reporting is rare. Very few people want to make it public that they lost coins due to their lack of secure methods or simply ignorance - humans dont like being called "fools".
If you are talking about exchanges getting hacked, then once every few months a certain exchange does get hacked and this has happened every year or so.
And then comes altcoin projects that end up with their vaults getting hacked or something similar. Not that rare I would say.
Good thing that people are so honest.
Yeah, about that, they are not. Since it is so easy to remain anonymous and still commit crimes here, it is rampant and the lack of anti-money laundering only makes it more difficult to trace. But they do get caught and often face charges, provided the money involved was big enough. For smaller retail bitcoin investors, you guys are out of luck for the legal route usually, so better secure your own devices and wallets.
