I won't accept it as a form of salary because it is really unstable at this time......

But if you consider the prices go higher levels then it might get you huge profit if you are saving them, then it must be good idea to get your salary to save some bitcoin with the intention of making huge profit in future. So, decide and get your salary in bitcoin.
And what will you do if price goes the other way? I mean if it goes again to $200 or $300 level in future will you still prefer to accept salary in bitcoins? As anything is possible in future so be wise before taking any decision.
