In my view this is total nonsense. The notion that a Trump presidency would lead to global market turmoil is based solely on wishful thinking by his opponents and is used as scare tactic against his potential voters. I think there will be no difference in market reaction between Clinton or Trump winning at all. Also, a market turmoil would require that something unforeseen happens. That is not very likely for a presidential election with a vast amount of polling data before the actual decision.
Another question is, if Bitcoin would be even used as a safe haven asset for capital flight during a market turmoil at all. That theory was widely circulated in connection with the Brexit, however no real proof was ever given. Of course Bitcoin attracts investment due to its non-inflationary properties. But it's possible that this effect is rather a continuous process than a sudden event.
