>Here we can see that 2014 has been a sad year for altcoins, since all the market caps have declined a considerable amount. More importantly we can see clear evidence that altcoins live a short lifespan, out of the top 10 altcoins only 3 kept their position at the top, the rest got replaced with newly hyped coins, Peercoin being the only exception. Thus, we conclude that investments in altcoins are very high risk, with a decreasing reward. With the start of 2015 and the drama with GawMiners and Paycoin, this year does not look good for any cryptocurrency other than Bitcoin.
eth will win though
btc has no scaling roadmap (lightning network isn't a scaling solution its basically a watered down raiden network)
