Money is unsafe anywhere, even in most well-protected bank vaults. The only difference is that with crypto it is solely you who are responsible for providing safety of your funds (backing up keys, using antivirus, avoiding clicking on phishing links and so on), while in banks you have to rely on a third-party security system. But the way, not only bounty hunters are being hacked - experienced traders also sometimes become the victims of hackers, whose methods od scamming people are becoming more and more sophisticated.
