One day you will get robbed by one of these exchanges, and you will blame bitcoins (or the bad man) and swear to never work with Bitcoins again. But they will be just one link in a chain of exchanges that you've trusted each one, hundreds of times, to bring you music and movies for bitcash, and nobody will write an article about it.
I am a small volume user but I have never been scammed by anybody in Bitcoin, except for that Bitscalper fellow.
