Then by all means, keep doing it
Once all XIV have been mined, in a few years, there will be 8.6 Billion. For comparison, Doge will be 800 Billion, i think (might be 100 Billion). So at least in Theory, 1 XIV should be worth 800 Doge. That explains the different results you get, while mining. It all depends on how many people are mining it right now (Doge is overhyped in my opinion, so there are a LOT more miners).
The "real" Value is based on normal market forces, though. Things like Trust and Interest in the coin, strong support, good network, how much demand and supply, etc.
Setting on XIV´s is a bit of a gamble, of course, since it is brand new and not yet on any exchange.
I wrote a post earlier, that got swallowed by my damn 6 minute posting limit, but I predicted Doge to drop in price dramatically. It was released on cryptsy for something like 0,076 micro btc. I bought a couple of thousand and sold them a few hours later at 0,180. Like I predicted, the market is flooded with Doge now, since a lot of people are mining them like crazy now and flooding the market. Its down to 120 now and will keep falling. Thats what I wrote in the lost post, and I was right.
Xivra in comparison had a nice, decent start, no overhype, just a lot of people who liked the honest way it was released. It´s a small thing, but a good sign. I got a lot of miners fast, who had been waiting for it, like myself.
Still it is a very good coin to mine, the pool is running smoothly, it is not overhyped, not many people jumping on the band waggon (yet), so even with a CPU you should get out some XIV, before an exchange like Cryptsy picks it up and many more miners come in. Then again, the price and demand will rise too, and if you have mined a decent number of those, you will be able to either keep them until price rises even more, or sell them for a decent win.
Just look at Doge now. Even with the price drop, they are still the most profitable coin to mine, have been for 2-3 Days now, ever since cryptsy started to trade them. But they will eventually drop in price and profitability, because all the miners just sell. The only ones profiting will be those, that mined early.
Same will be true here.
The only thing that COULD happen, a few months/years down the road, is that Xivra will become so accepted, like BTC and LTC now, and to a certain extent some other coins (like Frankos, for example), that you can buy real goods with them. But only few coins have that potential. Xiv might be one of them, who knows?
much awesome. such dog. 
,i want buy it, how about 0.1 LTC
