Is the GunCoin Network ASIC Miner friendly? Thinking about getting a BitMan compatible unit. Hopefully the next wallet version would also become POS.

GUN is NOT ASIC friendly by design (that is why we choose Neoscrypt) and will stay that way. There are no plans to make the current GUN into POS any time soon.
One can always mine whatever they want, with whatever they can, and then buy Guncoin with their proceeds.
I kind of like to place some buys in at Cryptopia and then let the autominers sell into them, feels kind of like they are mining for me, LOL.
We have quite a few autoswitch pools mining GUN on occasions. I have seen them switch on hundreds of miners at a time. While it does hurt our existing miners temporarily, it is great publicity for Guncoin.
