1. Stop. Deep breaths

2. Write down every single PIN you have tried. Right now.

3. Make a backup of that list.

4. Step away and don’t mess with it for a few days or weeks.

5. Continue looking everywhere you can think of for where you might have written down that seed. You may be remembering wrong. Keep that possibility open. Organize everything in a room if you need to. You’ll probably find something else anyway.

6. Think about what that fucking PIN code was a little bit every single day. Think about every single detail you can about what you were doing, wearing, where you were, etc. Pull every scrap you can together. Memories are triggered in weird ways sometimes.

7. Write down any other codes you think it might be when they come to mind. Make sure it makes it to your backup list.

8. Contact anyone who has any experience trying to physical hardware hack a Coldcard. See if there is any way possible to give yourself some extra space on the PIN.

9. Good luck.

In the future:

No matter what you do with ANY wallet. When you set it up, go through your entire seed and backup process. Literally every time. It really isn’t that long, it’s good practice to formalize it, and you will never regret it after the fact no matter what happens.

I’ve lost bitcoin this exact way. So I know what this feels like. Sorry dude, but it’s not over either. 🫡
