The Securities and Exchange Commission of Thailand has revoked Huobi Thailand's licence. Here is their statement:
The SEC’s inspection on the operation of Huobi as a digital asset exchange operator during February 2021 - March 2021 detected deficiencies and insufficiency in Huobi’s management structure and work systems, causing the company to fail to operate its business in compliance with the governing regulations.
They were given about a year to fix stuff, but they haven't, so they are being closed down on 1st July. If people have any coins there, they need to get them out before the end of June.
This was the only exchange that Thai Hivers could trade Hive against the Thai Baht.
