Proof of keys question

What is Proof of Keys anyway?

Why do I see that some say investors are being urged to move their cryptocurrency off of exchanges (Coinbase, Binance, etc.) and into a Bitcoin wallet where they have control over the private ?

My question is, what’s the advantage to using Coinbase, binanace etc. vs a bitcoin wallet?

Pros and cons to argument?

Thanks in advance
