How might someone memorize their seed if they aren't comfortable with recognizing 12 English words? Is there an alternative BIP39 encoding that's popular in non-english regions?

Our sub-indexes show that China is especially strong in usage of centralized services, placing second overall for purchasing power-adjusted transaction volume at both the overall and retail levels. This is especially interesting given the Chinese government’s crackdown on cryptocurrency activity, which includes a ban on all cryptocurrency trading announced in September 2021. Our data suggests that the ban has either been ineffective or loosely enforced.

China has been home to the largest chemical industry by revenue in the world since 2011. A 2020 Drug Enforcement Administration (DEA) intelligence report cited China as the top producer of fentanyl precursors in 2019. The DEA has noted a pattern of fentanyl production in which precursor chemicals are illegally shipped to Latin America, where they are used to manufacture fentanyl, which is then transported into the U.S. to be sold.

Due to recent law enforcement actions and sanctions, we know that many illicit actors involved in fentanyl-related transactions use cryptocurrency. To analyze these patterns at scale, Chainalysis identified cryptocurrency addresses associated with suspected China-based fentanyl precursor sellers. These addresses have received more than $37.8 million worth of cryptocurrency since 2018. Latin America, North America, Europe, and Asia exhibit a high degree of exposure to these suspected chemical shop addresses.
