One man accidentally tossed a hard drive holding $200 million worth of Bitcoin — and it’s still buried in a landfill.

Why? In Bitcoin’s early days, many people lost access to their wallets or simply forgot they owned Bitcoin.

How much is lost? Experts estimate that over 3 million BTC are lost forever, trapped in forgotten passwords and abandoned drives.

Why it matters: These lost coins shrink the effective supply, making Bitcoin even rarer than most realize.
