I do not expect it to be a trade war between the United States and China, but a power struggle to prove who stands up for the last moment.
If we assume that it is a trade war, the direct impact will be on the stock markets: starting with technology companies, the automobile sector and other related economies between the two countries.
The impact on digital currencies will be indirect because people are afraid of economic shocks, so they will resort to other means to save the capital from gold, silver, and cryptos.
cryptocurrencies are not a safe haven but high-risk investments, so I do not expect many investors to resort to it.
