If the United States imposes high tariffs on Chinese imports, then the smart decision for China is to retaliate. China is too big to be intimidated in this way.
This means that US corporations will likely face the impact of China's reaction, and that could be bad for the stock market and the US dollar, which could put pressure on safe goods such as gold and silver, and reasonably on Bitcoin. that would continue his behavior to date.
Companies that could be hurt by a trade war with China include Starbucks, Boeing and Apple, to name a few that have made huge bets on China.
China would be the far bigger loser. The USA is their largest importer by far, they rely on the US consumer. The price of our goods would go up, the but it would wipe out large portions of China's economy...which would be great considering most of their wealth is based on some form of sweat shop/child labor/slavery.
