Highly manipulated & that is the reason behind the "bull run" effect..that's atleast what I think about it. Dont get me wrong, there is still money to be made, but I wouldn't go so far to call it a bull run just yet...
Every bull run has its reason, maybe it's being manipulated or just people buying the hype again. As for the altcoin markets, I wouldn't say that we are in a bull run yet. Bitcoin is still dominating and to be able to say that we are in a bull run, the dominance should go to 45-50%. But so far bitcoin is having its day, around 60% or more today. So all we can do is to wait for the altcoin market to make its run independent of bitcoin, in my opinion.
