I've heard a lot about KuCoin recently, but I'm not sure how risky it is. As a professional in the field of cryptocurrency and finance, can you tell me what the risks are associated with KuCoin? I'm particularly concerned about the security of my funds and the platform's stability. Are there any known hacks or security breaches that have occurred on KuCoin? And how does it compare to other major cryptocurrency exchanges in terms of risk management and customer support? I'd appreciate your insights and advice.
