Could you please elaborate on the regions or countries where Binance is not allowed to operate? I'm curious to know the specific jurisdictions where this cryptocurrency exchange is restricted due to regulatory concerns or other reasons. Could you provide a brief overview of these locations, and perhaps mention any recent developments or changes in the regulatory landscape that might affect Binance's availability in these areas? I'm interested in understanding the global reach of Binance and any challenges it faces in terms of compliance and regulations.
