I don't think we are in danger of being hammered and dumped because in order to sell coins you have to have buyers and most of the buyers are holding on to their coins so the coins are not recycled. If anything these asics will just make it easier for people to buy coins and bring the diff up making it harder to mine them. In the end the coin will not be hurt, it will be the small miner that will truly feel the pain. Even then all they have to do is mine a different coin or algo with higher mining rewards and then just covert them to LTC and then buy Karma increasing the daily volume, at the same time taking the coins out of the hands of dumpers and holding them in their wallet for the shares benefit. And if all ells fails just buy a asic and mine karma. As long as you are not a dumper you will be making it harder for dumpers to profit. Once the value goes up high enough and the volume levels steady out, more coins will be held within our ecosystem and less will be dumped in big chunks.
I see your point, but I continue to say that if all people that believe in Karma mined it, then the interest of other miners would skyrocket.
Basically, difficult goes up very fast -> Everyone goes crazy and the price shoots up
Not that it is imperative in the long run...
