Which countries are banned from BitMart?

Can you clarify for me which countries are currently banned from accessing or using BitMart's services? Are there any specific regulations in place that prohibit individuals from certain countries from participating in cryptocurrency trading through BitMart? It would be helpful to understand the geographical limitations and any potential implications for users outside of these banned regions. Additionally, are there any plans for BitMart to expand its services to these countries in the future, or are there any challenges that prevent such expansion?
