Normally when Bitcoin is flying high the alts suffer and are all in red, what we have seen this past week is Bitcoin flying and the alts also flying.

Lots of people don't want to sell their Bitcoin and newbies can't afford Bitcoin (it's a physiological thing to want 1 full coin even though it's divisible, I think that's a reason for Litecoin's recent rise) so they are going for the cheap stuff hoping for massive returns and it's kind of working as it seems millions of others have the same idea which is pumping the prices up.
