Bitcoin Self-Custody & Security

Learn why buying bitcoin on exchanges gives you IOUs, not full sovereignty, and how self-custody storage protects your scarce crypto from exchange failures, cybercrime, and third-party risks.

Master self custody essentials, hot and cold storage, and security practices to protect your bitcoin, understand decentralized private ownership, and compare centralized versus decentralized monetary systems.

Centralized monetary systems rely on a central authority and custodial exchanges that issue off-chain IOUs, so you don't hold private keys or fully control funds.

Discover how off-exchange transfers settle in a decentralized block chain network, with tamper-proof distributed ledger across thousands of nodes, enabling secure crypto custody.

Explore self-custody where you own and control your Bitcoin via a private key in a non-custodial wallet, accessing a distributed ledger without middlemen.

Explore how crypto wallets interact with the blockchain, compare hot and cold wallets, and learn about keys and recovery seed phrases for secure self-custody.

Understand private and public keys in crypto, where asymmetric cryptography links keys to allow sending and proving ownership while enabling others to verify signatures.

Private keys grant ownership access and must remain private to protect funds on the blockchain. Keep your private key secret; it unlocks your wallet and authorizes transactions, never share it.

Learn how a public key pairs with a private key to receive or transfer funds in peer-to-peer and wallet contexts, enabling decryption and identity in cryptographic messages.

Explore how a public address is a hashed, compressed form of public key, how wallets derive accounts from private keys, and how self-custody secures keys for sending and receiving transactions.

Use seed phrases as the recovery phrase for private keys. Provide a 12- or 24-word backup to safeguard funds if a wallet is lost or damaged.

Explore hot wallets as non-custodial software and desktop wallets to safeguard your keys and manage everyday cryptocurrency transactions on a distributed, decentralized blockchain network.

Understand desktop software wallets like Armory, Exodus, Garda, and Electrum to control private keys, send and receive crypto, and securely store assets on your device.

Mobile wallets turn your phone into a personal crypto vault for on-the-go payments with QR scanning, but require internet access, and backup seed phrases to avoid loss and malware risk.

Master hot wallet security with practices like using a VPN, enabling two-factor authentication and OTPs, and securing a backup phrase or private keys. Double-check addresses and amounts before sending.

Cold storage keeps crypto keys offline in a physical form for self-custody of larger amounts. Paper, metal, and hardware wallets each demand different technical skills and steps to secure funds.

Use offline paper wallets to store a private key and a Bitcoin address; generate offline with a trusted wallet and printer, then store securely, aware of loss and other risks.

Secure your private keys with a hardware wallet, a portable offline device that signs transactions on a certified security chip for true self-custody and keeps funds off the internet.

Evaluate metal wallets as durable, offline cold storage for seed phrases, covering materials like aluminum, steel, titanium, testing under extreme conditions, and security tradeoffs like loss or theft risk.

Apply a five-point storage security checklist for Bitcoin self-custody, balancing holdings size, budget, and risk tolerance with appropriate hot, cold, and multi-sig wallet options.

Master self-custody dos and don'ts for bitcoin wallets, including protecting private keys and seed phrases, securing backups with paper or metal, using hardware-backed password managers and two-factor authentication.

Discover how Bitcoin enables personal sovereignty and being your own bank, while balancing secure self-custody with awareness and protection against scams and breaches.

Develop crypto security by building a self custody model that fits security range, using the self custody checklist, and hodl safely with secure storage to be your own bank.
