Should I trust or leave my Bitcoin on an exchange?

Should I be placing my trust in leaving my Bitcoin holdings on a cryptocurrency exchange, or should I consider moving them to a safer alternative? I'm concerned about the security measures implemented by exchanges and whether they can truly protect my assets from potential hacks or malicious actors. Additionally, I'm also worried about the potential for exchanges to go offline or become insolvent, leading to the loss of my investments. What are the key factors I should consider in making this decision, and are there any reliable ways to determine the safety and stability of an exchange?
