FAQ
What is the best bitcoin-only wallet?
On this rubric, Coldcard scored highest. Your answer depends on your priorities; adjust the weights in the tool.
How does VaultRubric score platforms?
Each criterion gets 0–10 from cited evidence (curated dated data, live independent reviews, and AI analysis that must quote its source verbatim). Weights are normalized to 100%; missing data is excluded and shown as coverage. Platforms with an unreimbursed customer-funds hack in the last 48 months are capped at 60% and can't be the pick. Criminal guilty pleas (−2) and major civil settlements (−1) in the last 5 years reduce the security score.
