We can only wait and see. There are already altcoins which have been soaring really high for the past weeks. But still the strongest right now is Bitcoin so it is normal that altcoins' rally will not be as strong as Bitcoin. But who knows what happens to them when Bitcoin creates an all time high? Perhaps a lot of Bitcoin owners will sell some for altcoins. When Bitcoin corrects the altcoins will receive the money diverted.
Staying affirmative on some of the coins being bought early and looking forward for some good run to happen in altcoins. Currently the altcoins season has not being started it seems due to which some coins inspite of renowned coins are falling and also buying at dips is good things since once it starts to rise it will be rising very quickly.
