Yeah they did not add WC on Craptsy for nothing, I expect a pump cause of this.
Might wonder that Mintpal adding WC without voting and now cryptsy, that they are not behind some organised pump dumps lol
Or maybe they added them because they are hugely demanded and high volume coins and since they are exchanges, and make money by letting customers trade coins, they added WC so they could make some fees?
the simple answer is usually correct, not the conspiracy
