Should I keep my crypto on Coinbase exchange?

Should I be concerned about keeping my cryptocurrency holdings on Coinbase exchange? I understand that they're a reputable platform, but with the recent hacks and security breaches in the crypto space, I'm wondering if I should take extra precautions. Is it SAFE to store my digital assets on an exchange, or should I consider moving them to a hardware wallet for added security? And if I do decide to move them, what are the best practices for doing so securely?
