Yep people get scared easily today
Big exchange like Gox falling down is a big thing. 744,000 BTC stolen is also a very big thing. Who says this can't happen again with one of the other big exchanges?
This is why we need a decentralized exchange, owned by nobody. The Mastercoin Foundation is creating the first. And I am quite certain there are more in the pipeline.
Centralized exchanges will be a remnant of the beginning stages of Bitcoin.
Growing pains. Stay the course. Much good to come.
