Looks like after two months only two of the altcoins have outpaced BTC, I'll be curious to see how this thread looks in the end of 12 months, I suspect a similar trend will remain.
It's 10 months, not 12.
Do you have any suspicion why PPC and ARDR were able to succeed where the others failed?
Luck? I don't think there's much logic behind cryptocurrency prices.
Both coins already lost their profit. Alts are getting slaughtered with Bitcoin up more than 30% in just one day, and many alts going down 30%.
