to be honest, I never knew that Mt Gox was an exchange, because I thought it was like a Financial Institution. And more surprisingly, the record of Mt Gox in terms of hacking is truly astounding. Have those who have been in it never learned about the importance of security exchange that must be truly fulfilled? very sad for victims of hacking the exchange above.
I remembered when I was a newbie here, Mt. Gox was the first one of the big exchange on which I had been heard that has been hacked. Actually, when this things was broadcast here it is a big news here in crypto industry. And aside from this, As far as I know Etherdelta also has been hacked more than once too, I just wondered why it didn't list here.
