When the bitcoin price is increasing too much it's really a common thing to see that there's no action from other altcoins. That is the always happening everytime there is a situation like that.

There is no people who can give an accurate answer here since all are unexpected. If you have spare amount and really confident that soon other alts will rise again, then give it a shot and see what will happen.
