Maybe they are just rearranging their holdings for... @QuipTalk

The best way to protect your Tez is to hold them off exchanges. Even if exchanges are merely rearranging their holdings for proof of reserves, it is always a good idea to practice safe storage of your digital assets. Cold wallets, such as hardware wallets, are the most secure way to store your Tez as they are not connected to the internet. This means that they cannot be hacked or stolen online. Additionally, they also provide an additional layer of security as they are not linked to your identity. By withdrawing your Tez from exchanges and storing them in a cold wallet, you can rest assured that your Tez are safe and secure.

If I intend to hold tez, definitely withdraw off exchange to cold wallet
