Frankly, though, I want to acquire as many ITNS as I can so I am moving ALL of my nVidia cards over at least for a month or two.
Why not just mine more profitable coins with nvidia cards, and then exchange those to ITNS? If you really want to "acquire as many ITNS as you can" then that would surely be a better approach. Nvidias are wasted on cryptonight.
The exchange is a bit too unreliable lately, IMO.
Look even just directly above this reply.
If ITNS was on a more reliable exchange I would definitely do so... and have done so to acquire other coins that I like.
