The only way that your account can be hacked is if you give out your password knowingly("Hey! I'll get you free toriprime!") or unknowingly(Phishing sites) or someone gets hold of a copy of the database. I don't remember if it is encrypted or not. You're pretty safe here. Just use your brain.
Bank accounts tend to be less secure, because generally if they get hacked it takes too long for you to figure out that that's happened.
It IS encrypted. And if they were using brute force attacks, I'd be perfectly fine with that.
Do you realize, to brute force even the weakest commonly used algorithm today on a computer that could calculate the algorithm a billion times per second, it would require a period of time longer than the present age of the universe by a factor of a billion?
It's rather unfortunate stronger attacks exist against that algorithm.
