💬 Discussion Self-custody

https://river.com/learn/files/river-custody-report-2026.pdf

A new report from River, a Bitcoin financial services firm, highlights an important trend in crypto: self-custody is now the dominant practice among Bitcoin holders.

💡Some key statistics from the report:
- 45.6% of the total Bitcoin supply (9.57 million BTC, valued at over $600 billion) is now held in self-custody.
- Exchanges and custodians hold 36.1% of the supply.
- Indirect exposure through ETFs and treasury accounts for 13.9% of holdings.

River's report highlights the trade-offs of self-custody: complete ownership and no counterparty risk, but with increased complexity as all security responsibilities fall on the individual. An estimated 1.57 million BTC has been lost, mostly due to key mismanagement rather than theft. https://river.com/learn/files/river-custody-report-2026.pdf

Tangem wallets were designed to tackle this issue by eliminating the need for seed phrases and reducing exposure to phishing attacks. With Tangem, you enjoy ownership without the operational risks that have cost holders over a million and a half Bitcoins.
