Underperforming? Where?
Did you see the charts from the last summer? Every altcoins made bigger growth than Bitcoin. Tell me if you find which altcoins did not.
I mean just over the past few days. say 1st Jan 2014~today.
LTC/BTC 0.031 -> 0.028
FST/BTC 0.000027 -> 0.000023
QRK/BTC 0.00014 -> 0.00010
ZET/BTc 0.000050 -> 0.000037
XPM pretty good though,
PPC, NMC very good... (I didn't buy at all, I didn't like 10 minutes block gen time...)
BTC is going up up same period.
My bad choices of coins?
It seem none choice of altcoins was bad
Now you can calculate how much your coins made from the last summer, and you will see what I said.
I think altcoins are capable to do much bigger growth than Bitcoin. Reason? For 1 BTC i can buy thousands and thousands altcoins of all kinds
Some are really good opportunities, I think.
