Why is OKX popular?

Could you elaborate on why OKX has gained such widespread popularity in the cryptocurrency space? Are there specific features or services that set it apart from other exchanges, or is it perhaps due to its user-friendly interface and robust security measures? Additionally, how does OKX's diverse range of trading pairs and financial products contribute to its overall appeal among traders and investors? I'm curious to understand the key factors that have contributed to its success and widespread adoption.
