In this brief YouTube interview, Mark Moss recounts three distinct incidents where he lost Bitcoin: a large theft from an exchange, a hot‑wallet compromise on his phone, and a cold‑wallet that became inaccessible due to a missing PIN after a firmware update. Reflecting on these failures, he explains his current approach to protecting his holdings: splitting assets across multiple hardware wallets, employing a multisignature setup, and keeping smaller balances on various custodial services such as River, Coinbase, and Venmo for transactional convenience. The conversation underscores the importance of diversification and layered security in personal cryptocurrency management.
