According to the latest report from blockchain analytics provider Coin Metrics, nearly 1.7 million Bitcoin have been lost due to duplicate transactions, unclaimed rewards, or theft. At Bitcoin's current price of ~$8,000, this equates to ~$136 billion in lost value.
How Bitcoin Gets Lost
Coin Metrics categorizes lost Bitcoin into two types:
Provably Lost Bitcoin
- Permanently verifiable as lost (e.g., sent to invalid addresses).
Probably Lost Bitcoin
- Highly likely permanently inaccessible (e.g., private keys discarded).
Bitcoin’s Fixed Supply Scarcity
- Total supply cap: 21 million BTC (set by Satoshi Nakamoto).
- Circulating supply: ~18 million BTC mined as of October 2019 (per CryptoSlate).
- Remaining: 3 million BTC (~14.3%) left to mine.
Mining Timeline Highlights
- First 1 million BTC: Mined in 200 days (2009).
- Final 3 million BTC: Estimated to take until 2140 due to halving events.
The "Dead Coin" Factor
Even when all 21 million BTC are mined:
- ~75% maximum circulation: Up to 20% may be permanently lost ("dead coins").
- Primary causes: Lost private keys, forgotten wallets.
👉 Why Bitcoin’s scarcity could drive long-term value
Market Context
- Recent price drop: Bitcoin fell below $8,000 (October 2023 lows).
- Competition: Stocks/bonds/gold saw double-digit gains in 2023, reducing crypto demand.
FAQs
