Des portefeuilles matériels aux coffres-forts institutionnels

Self-custody has moved far beyond the simple hardware wallet. The custody landscape in 2026 is stratified, offering solutions for every level of user and wealth. For individuals, multi-signature (multisig) setups using 2-of-3 or 3-of-5 schemes are becoming standard practice for significant holdings, often coordinated through user-friendly apps that abstract away the complexity.

For institutions and high-net-worth individuals, a new industry of geographically distributed, deep cold storage vaults has emerged. These involve sharding private keys across multiple secure jurisdictions, using a combination of biometrics, physical security, and time-locks. The most cutting-edge development is the integration of MPC (Multi-Party Computation) technology, which allows transactions to be signed without ever reconstructing a full private key on a single device. Meanwhile, regulatory-approved "qualified custodians" offer insured, audited services for ETFs and funds. This spectrum—from simple mobile wallets to fortress-like institutional vaults—means security is no longer the primary barrier to holding large amounts of Bitcoin.

For your main Bitcoin holdings, what is your custody setup? Has it evolved since you first bought Bitcoin, and do you trust third-party custodians more or less than you did a few years ago?
