From a recent quarterly review

The workbook listed every seed-storage location in my apartment and flagged that two envelopes had the same outer label. We fixed that before opening either device. I still wish the session had started earlier in the day—I was tired by the recovery drill.

— Hyeon J., hardware wallet holder, Suwon

I hold mostly long-term positions and rarely trade. The checkpoint pack forced me to write down what each wallet was actually for, which cleared up a mess of duplicate addresses I had been ignoring.

— Marcus L., self-custody since 2017
