I only see this trade war as something that may hurt the price of Bitcoin -- if it goes sour. Think about it like this, if the price of traditional investments is to decrease substantially. Then you're going to see speculative investments such as Bitcoin, and other high-risk investments start to go through more of a sell-off because people need liquidity in their other assets.

This would carry the assumption that those that invest in Bitcoin, have holdings in traditional investments as well. That assumption may not (fully) be true which would nullify the rest of what I've said.
