Does BitMart charge a fee?

I'm curious to know if BitMart imposes any fees on its users. Are there any transaction costs associated with buying, selling, or trading cryptocurrencies on the platform? It's important to understand the full cost structure before investing, so I'd appreciate it if you could clarify whether BitMart charges fees and, if so, what those fees entail. Additionally, are there any hidden costs or fees that users should be aware of?
