Interesting article, thanks for posting.
I also think that some smaller exchanges might dissappear soon. One should also keep in mind that with last year's hype many man new exchanges came into live. Now with the bear market only the best (biggest, most profitable, securest) will survive and some will dissappear. It's just the normal "business cycle of life"
Actually, as investor we need to be fully care to new exchange because of security. This is first reason and second is the new exchange has not enough volume and as trader, low volume of exchange is really not interest since it means the exchange has no popularity. Thats the reason why we should be care.
