What would a normal, rational-thinking person do? It would get off the exchange as soon as possible, in my opinion. It would try to exchange BTC to fiat and move out as long as there is more clarity about the current situation.
The only thing that is clear about fiat (be it USD or Euro or Yuan) is that they will keep printing more and much more of it. So why exchange to fiat and leave? That would not be rational thinking.
