My suggestion is to don't take any decision with panic just wait for only few days definitely you will get a great profit because very soon market will go up. if you sell your coins now then you might regret your decision and crypto market will never shut down at any moment.
I think soon we can expect a real panic due to the fact that altcoins and bitcoin will fall sharply still much lower. The most important thing to survive this moment and not give in to panic.
