Sure it could, but no I don't think any correction that happens in any raging bull market is cause for concern.  There's been absolutely no negative news and nothing I can see that would pop this bubble (it might not be a bubble, but you know what I mean). 

People are just taking their profits off the table after having made a lot of money--and there are probably silly panic sellers as well driving the price down.  But all in all I don't think the bull has stopped charging; it's just taking a breather and will resume once it catches its breath.  I'm thinking bitcoin could probably be near $75k by the end of the year, but we'll see.
