Is BitMart a Tier 1?

Could you please clarify if BitMart is considered a Tier 1 cryptocurrency exchange? I'm interested in understanding their position within the industry and how they compare to other major exchanges. Tier 1 exchanges are typically known for their high trading volumes, strong security measures, and reputation in the crypto space. So, would you categorize BitMart as a Tier 1 exchange, or do they fall into a different tier based on their current offerings and performance?
