The same thing that has been happening for more than years.
Bitcoin will recover first, and once that it is a little bit more "stable" all the altcoins are going to follow up the bitcoin trend.
I am looking forward to hear your opinion. In case (and this is my expectation) BTC goes up first, it might be wise to allocate your funds in this way!
Actually this time all serious and good alts are recovering hand to hand with the Bitcoin.
Bitcoin is not the King anymore...
