Bitcoin trend is the opposite trend for the all of the altcoin, if the bitcoin will be having a new price and soon all of the altcoin have needed to adapt to such condition. Bitcoin is the root of all alt in this time, bitcoin can be disturbing itself anytime.
I don't think so, Altcoins tend to get independent of Bitcoin, the main reason is that these technologies are completly different, you can't judge an altcoin like you would do for Bitcoin.
Have a look at Ripple, the price is around 1k satoshi for 1 XRP, there are 15 Billion XRP holded mainly by the central autority, it means that roughly the Rippl's market cap is 150k
BTC, does it means something for them ? i don't think so, and it is the same thing for all legit altcoins.
You can compare Bitcoin with other SHA256 cryptocurrencies meant to be used in the same way, like IXcoin hwo has been abandoned by the miners because of 0 block reward, and stuck at a verry high diff, this may be the next issue the bitcoin will have to face, and here, you can compare both of these coins.
Don't do the mistake to compare Bitcoin with ETH/ETC or NXT or WAVE, it is not the same at all.
