I would be very interested to point some of my CUDA processors at DIG before ASICS hit the scene. Does anyone know if there is any Linux software available capable of mining DIG right now or in development?
Nope, because DIG is not minable.
If it's not minable, then what's the point of their building a NVidia/AMD mining rig facility?
Mining facilities are to mine bitcoin and other major altcoins. DIG and other cryptobontix tokens are backed by precious metals. The mining of other altcoins is used as a strategic profitable investment effort to increase their ability to buy and mine more precious metals to back the cryptobontix tokens as well as to buy back their own tokens from the open market in order to decrease their supply and increase their value. I think ECHO (Reciprocation) will also be backed by some of the other alt coins they mine though I'm not totally clear on that.
The Cryptobontix alt tokens are not mineable because they are simply releasing a fixed amount all at once.
If there are mistakes in my understanding of this or what I've said, somebody please offer corrections. I have read both whitepapers but I'm not sure I've got it all 100% correct.
Most of that makes sense but for the full fixed amount released. There is still the matter of needing to reconcile a coin swap for holders of UNY at C-Cex, coins which technically are already in circulation.
