Bitcoin is the king. If you analysis, only bitcoin is must bullish for last 10 days while rest of the altcoins are not moving at the pace at which bitcoin is pumping.
Ethereum is the other one which is pumping because of its hard fork news.
First and only, Always was, is and always will be:)
It's actually ETH that's hugely more bullish than Bitcoin in the past 10 days, though, and I think some other alts have been making crazy moves too, but all that's precisely because Bitcoin is making the foundations for them. See even the sudden crash yesterday, reflected in ETH and all other cryptos.
