“Get off zero” is the reminder to stop having a 0% allocation to bitcoin in your investment portfolio.

There is another one that’s equally as important but not that many realize it: 

“Get off 100%” 

This means get off 100% dependency on third-party servers and apps. Understand the implications of having all of your digital life stored in someone else’s computer/server (i.e. Apple, Google, AWS). Self-host via a @Start9, use @GrapheneOS on an Android phone, use a Linux distro. It’s not that complicated, just takes time and dedication, just as understanding bitcoin. 

 100% might be agressive, at least as things are today, but the more the better! 

 Correct, I meant to start reducing your 100% dependency. Not sure we'll ever be able to get off 100%, but its all about reducing that percentage to the least possible while still being a functional human being of society.
