Is it safe to leave money in KuCoin?

I've been considering investing in cryptocurrency and I've heard a lot about KuCoin. But before I take the plunge, I'm wondering - is it safe to leave money in KuCoin? What kind of security measures does the platform have to protect user funds? Have there been any reported incidents of hacks or thefts? And how does KuCoin compare to other crypto exchanges in terms of safety and reliability? I'd really appreciate some insights from someone who knows the industry well.
