<p>Cryptocurrency exchange Huobi Global announced today that it will freeze all U.S. user accounts starting Nov. 13. </p> <p>The exchange said it has been "gradually [disabling]" U.S. accounts to prevent trading and transferring. U.S. users are advised to return their borrowed funds in margin trading and withdraw all assets from the platform. Those who purchased Huobi's pre-paid cards will be refunded in USDT, according to a company blog post. </p> <p>The account purge does not mean that Huobi Global will exit the U.S. market, however. Huobi has a <a href="https://www.theblockcrypto.com/daily/8009/huobi-aims-for-us-market-following-rebrand">strategic partnership</a> with San Fransisco-based HBUS, a platform dedicated to serving U.S. customers. Similar to Binance.US, HBUS runs a separate order book from Huobi Global and operates independently from the larger exchange. </p>
