Deposit Only Wallets Hidden Quantum Defense + Coinbase Migration Breakdown

In this video, I break down a real debate from my livestream around deposit-only Bitcoin wallets and whether they provide theoretical long-term protection against quantum-based attacks. Plus, we connect that directly to Coinbase’s recent internal wallet migration strategy, which aims to reduce exposure of known public addresses over time. 🔐 Key points covered: ▫️Why a deposit-only Bitcoin wallet never exposes its public key (until first spend) ▫️How Ethereum public keys become exposed much earlier through transaction signatures or software wallet interactions ▫️Why hardware wallets can delay public key exposure, unlike MetaMask and most hot wallets ▫️What a “harvest now, decrypt later” attack actually means in the quantum context ▫️Why Coinbase regularly rotates its internal wallets as best practice 👉 This is not FUD. Quantum cracking is NOT an immediate threat. But wallet structure now affects future resilience. 🛡️ LEDGER BLACK FRIDAY DEALS ARE LIVE NOW! 👉 https://shop.ledger.com/r/cryptodad?r... 🛡️ Secure Your Crypto This Black Friday!
