From the article itself:
Roughly 20% of new Bitcoin is mined in Xinjiang, the site of some of the world’s most egregious human-rights abuses. Today, Bitcoin’s association with Xinjiang is barely discussed. But that may change. For public-facing funds considering investing in the notoriously volatile asset, there are two other risks to consider. The first is that because of the concern among the American public about human-rights abuses in Xinjiang, holding assets tied to the region comes at the risk of a public relations disaster.
Already, activists have criticized Olympic sponsors for participating in the “genocide Olympics”—the 2022 Beijing Winter Games. Multiyear campaigns to hive Xinjiang off from the global supply chain are already well under way.
I would expect to see more articles shedding light on this in the future.
