Coinkite founder NVK and Bull Bitcoin founder Francis Pouliot break down the most critical privacy vulnerabilities in Bitcoin today, why kidnappings tied to crypto wealth are surging across Europe (one every four days in France), and the technical solutions finally closing the gap. From silent payments and async pay join to BIP322 proof of reserves and UTXO management, this is the most comprehensive Bitcoin privacy conversation of 2025. Learn why giving your xpub to an exchange is catastrophic, how 5% pay join adoption could break chain analysis entirely, and why Nostr disposable identities may be the missing piece for private payments.
