"None of them are of relevancy"

You are right to a certain extend, greed is the short term engine and whatever coin you hold is the one you are going to defend. I though Yacoin were a good shot because of the CPU only capacities. Obviously the savage pre-mining and 5 days to release the ss3 and amx algos made a lot of people end up with scrapes while others have millions. Still the potential is enormous because anyone with a CPU can get in.

Given that significant portion of the Yacoin 2.8M coin universe can be bought at 0.0005 or 200K USD there isn't much barrier to entry in YAC. The coin was so well distributed that record number of early miners want to sell their proceeds for cheap. The launch was truly a CPU race and no one won millions.
