How legit is OKX app?

Could you please elaborate on the legitimacy of the OKX app? I'm interested in understanding its credibility and reliability as a platform for cryptocurrency transactions. What kind of security measures does it have to protect user funds? Are there any red flags or concerns about its operations that investors should be aware of? Additionally, how does it compare to other popular cryptocurrency exchanges in terms of features, user experience, and trustworthiness? I'm considering using it for my crypto trading, but I want to make sure it's a trustworthy platform. Thank you for your insights.
