I think there will not be the 4th market, because CENT not trading anywhere alse like XPM or LTC...
It is possible, Cryptsy is a trading platform and always searching some ways of income and better market
With CENT cryptsy will have a very good opportunity of gaining a lot,
Profit from stakes is best and first part for them so very soon we will be able to trade CENT as 4th market.
anyway it very hard to broke even .002 satoshi wall...
