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"
Exactly it makes perfect sense if you analyze it objectively. Unfortunately for those exchanges getting started last year because if the bull run had continued they would be prominent in this space. But because things took a turn for the worst and most cryptos were overbought this was inevitable.
