The 5 Bitcoin insurance categories
Lloyd's syndicates underwrite the custodian (HashKey, Sygnum, Zodia). Covers theft, insider attack, key compromise of the custodian's infrastructure. You benefit if you're a client.
A few exchanges (Coinbase, Gemini, Kraken, OSL, HashKey) carry Lloyd's coverage. Self-funded reserves (Binance SAFU) are NOT independent insurance — they're discretionary funds. Read disclosures carefully.
AnchorWatch holds one key of your multisig + carries Lloyd's policy that pays out if their key is compromised OR if you lose your keys (subject to specific conditions). Unique in the retail market.
Nexus Mutual, Sherlock, Risk Harbor underwrite smart-contract failure on specific protocols. Limited capacity, exclusions for oracle manipulation, governance attacks. Useful for high-conviction DeFi positions.
A few specialty insurers (Coincover, Chubb's tailored crypto wrappers) cover hot-wallet theft for individuals up to specific limits. Premiums high, exclusions broad. Only practical for HNW with audit trail.
If you lose your seed phrase and have no backup, no insurer will reimburse you. Mitigation = multisig + geographic key separation + annual recovery testing, not insurance.
What's actually insured at major Asian custodians

| BitGo Japan | Theft, key compromise | Lloyd's via BitGo global policy | $250M aggregate |
| DBS Digital Custody | Bank-grade comprehensive | Bank insurer pool | Per bank coverage rules |
| OSL (HK SFC) | Theft, fraud | Lloyd's via VASP requirement | ~$50M aggregate |
| Coinbase International (SG/HK clients) | Hot-wallet only | Lloyd's | $255M global pool |
| Gemini Trust | Cold storage | NYDFS-required + Lloyd's | $250M+ |

Important: Insurance covers the custodian's losses, not your losses if the custodian becomes insolvent. Bankruptcy = unsecured creditor claim. Verify segregated-account legal structure separately from insurance.
AnchorWatch — insured multisig deep-dive
What it is
AnchorWatch operates a Lloyd's-syndicate-backed insurance policy that pays out if you lose access to your BTC due to specific covered events. They hold one key in a 2-of-3 multisig setup; you hold the other two keys. Policy term: 1 year, renewable. Premium: approximately 1.5% of insured value per year. Maximum coverage: $25M per client.
What's covered
- AnchorWatch infrastructure failure (their key compromised, service insolvency, key destruction)
- Documented loss of one of your two keys (subject to investigation requirements)
- Specific death scenarios (paired with estate plan)
- Forced disclosure under specific legal coercion
What's NOT covered
- You lose ALL of your keys (insurance can't recover what was never knowable)
- Voluntary transfers (you sent BTC to a scammer)
- Phishing where you revealed your seed
- BTC price decline
- Loss of access to AnchorWatch through your jurisdiction's actions against the service
Best fit: Asian HNW Bitcoiners with $200K-$25M in BTC who want institutional-style insurance combined with self-custody sovereignty. Less suitable: under $200K (premium economics don't work); over $25M (need multiple policy stack).
Asian-jurisdictional notes
MAS-licensed custodians (Sygnum, Coinhako Trust, DBS Digital) carry comprehensive insurance. Retail self-custody is uninsured but the licensed-custodian alternative is sound. Bitcoin holders >$500K should consider AnchorWatch or similar.
SFC requires VASP insurance minimum. HashKey, OSL, Hex Trust all exceed minimum. ZA Bank + Mox use bank insurance pools. Insured-multisig (AnchorWatch) accessible to HK residents.
FSA mandates exchange + custodian insurance. SBI VC Trade, bitFlyer, Coincheck all insured at multi-million-USD levels. Domestic key-loss insurance products limited; AnchorWatch accessible.
FSC + FIU require exchange insurance via the Virtual Asset User Protection Act. Korean retail can use AnchorWatch via cross-border setup.
VARA-licensed custodians (Zodia, Hex Trust, Liminal) all carry Lloyd's coverage. Best-in-Asia institutional insurance environment. Sharia-compliant insurance products via Wahed, Takaful Emarat extending to BTC.
No retail insurance products. Cross-border AnchorWatch onboarding limited. CoinDCX Prime carries partial coverage; WazirX coverage damaged by 2024 incident. Indian Bitcoin holders rely on cold-storage discipline rather than insurance.
FAQ
Can I insure my hardware wallet against fire/loss?
Yes via homeowner / contents insurance for the device itself (~$100). The BTC value on the device is not covered because insurers cannot verify ownership without the seed. The right answer is multisig with geographically separated keys, not insurance.
Is my Binance balance insured?
Binance maintains a "SAFU" emergency fund (~$1B BUSD/BTC). This is NOT an independent Lloyd's policy — it's a discretionary reserve that Binance chooses how to deploy. Treat it as soft assurance, not insurance. For real insurance, hold BTC at Coinbase, Gemini, Kraken, OSL, HashKey, or self-custodial multisig with AnchorWatch.
Will my homeowner's insurance cover BTC theft?
Most Asian homeowner policies exclude digital assets specifically. A few specialty policies (Chubb in some markets) offer extension riders for crypto, typically capped at $5K-$25K. Insurers ask for seed-handling and storage documentation — most retail users find compliance too cumbersome.
What's the cheapest way to insure $1M of BTC in Asia?
Self-custody multisig (Casa Diamond tier, $5,800/yr, no Lloyd's policy) provides operational resilience without insurance. Insured option: AnchorWatch at ~$15,000/yr Lloyd's-backed. Bank custody: Sygnum / Hex Trust at ~0.5-1% AUM/yr ($5K-$10K) with bank-grade insurance. Pick by operational comfort vs cost.
Are Bitcoin ETFs insured?
Yes — Hong Kong + US spot Bitcoin ETFs hold BTC at insured custodians (Coinbase Custody, BitGo). Your ETF shares represent a beneficial interest. ETF wrapper itself has SEC/SFC investor-protection regimes. Net: ETF is a high-trust path but you give up self-custody benefits.
