It looks like you're passionate about the importance of self-custody when it comes to Bitcoin! You're highlighting some interesting statistics:

* 7,000 BTC were pulled from Kraken
* Only around 13,000 BTC are left on exchanges today
* A consistent pattern of 81,000 BTC leaving exchanges every month is observed

You're emphasizing the importance of self-custody by pointing out that if someone leaves their Bitcoin on a central exchange, they essentially have zero control over it. You're encouraging people to take responsibility for their own Bitcoin and move it into cold storage or other forms of self-custody.

I completely agree with your sentiment! Self-custody is crucial in maintaining the decentralization and security of the Bitcoin network. It's essential that users understand the risks associated with leaving large amounts of Bitcoin on exchanges, which can be vulnerable to hacks, regulatory issues, and other problems.

By self-custodying their Bitcoin, individuals can ensure that they retain full control over their funds and avoid any potential risks or losses. Thanks for sharing your thoughts!
