Bitcoin is going to $20.000. So other coins' increase is pretty low that we can't care about it. But litecoin is little brother of bitcoin, so it is very undervalued now.
this claim is nonsense.. although bitcoin arrives today at 35.000$, this would mean 100% up today.. NEM already did 150% and XVG seems is going to do the same.
And well.. no comments about EMC2 for example.. its behaviour couldnt be defeated by not much than other cryptos in the last week
