Testing my equipment to mine CLO, I will see later if mining this is profitable or not. Whatever the result will be, will determine if I will continue or not. However, if I will not mind the results, I'm mostly optimistic Calisto will eventually get valuable in time. So good luck to me then. 
Unprofitable for sure!Not only Callisto Network, but also other minebale altcoins.
However, if you have strong belief in future development of Callisto Network and electricity bills are not your issues, you can keep mining, holding your coins for a long period of time to take profits.
