How do you know that this isn't inside job?
In my opinion if hacker steal money from exchange it is not your problem and they have to pay back whatever users lost.
This is why all exchanges have their privacy policies and terms reflect that they are not responsible for any outside breaches made to their networks.
You don't. Hacks target the exchanges wallet by finding exploits and not the user accounts separately. If you want your funds to be safe, use exchanges for trading only and withdraw to your personal wallet.
I love it when people say this. How the heck do you 'trade' if you keep your coins in the wallets... You don't.
IF you're holding, then yes, keep it in your wallet. If you trade it makes no sense.
What I meant is do the trade and withdraw instantly. Exchanges were created for trading and not for holding your funds. Unless you are day trading, I see no reason on why you should keep your money on an exchange for a anything more then a few minutes. Trading with individuals on forums etc. is another option to avoid using centralized exchange.
I think we're at a pivotal moment where a lot of the new adopters of crypto trading don't have a clue what Mt. Gox was. I love when people criticize the people who advise others not to keep their money in exchanges. Just because an exchange offers 2fa options, and verification on your account, doesn't mean that they can't get "hacked". Like so many others have said, I also believe that anytime an exchange gets "hacked", it's just an inside job for the devs to make a few million bucks. And for reference as to why a lot of early adopters ALWAYS recommend pulling your money out of exchanges (outside of trading), here's the wiki link to Mt. Gox:
