I still don't understand why are people keeping bitcoins on MtGox in the first place? It's not like they are going to get any interest from MtGox from doing so.

I still don't understand why are people keeping bitcoins on MtGox in the first place? It's not like they are going to get any interest from MtGox from doing so. If you need to buy/sell bitcoins then just send them to MtGox and retrieve immediately after transactions. Just keeping money, either virtual or real in someone elses wallet is not a good idea, especially if you don't get any benefit, only potential risk. I'm not blaming the victims here, just can't understand the reasoning behind. Then again, I have never used MtGox, so I might have been missing something.
