Why stop there. Though I find it difficult to rationalise a scenario where any of the current alts are worth their $values without this btc rally
Actually this crypto rally is driven by alts and not XBT. XBT market dominance is plunging
http://coinmarketcap.com/charts/#btc-percentage This is very different from the past.
Sure, the alts are driving the this general crypto rally/bubble, whatever you want to call it but you cant seriously think that if btc was down in double figures that we would be seeing $100 ETH, $20 ltc etc etc.
All the market share figures are showing is that the alts are outpacing btc in terms of % gains but the real world $ figures would be orders of magnitudes lower if btc wasn't so high. Imo thats undeniable.
