What happens when crypto is lost?
Crypto is lost when nobody can produce the private key or seed phrase that controls it. The coins still exist on the blockchain, but they can never be moved again, and no company, developer or network can restore them.
What it means for you
If you hold your own keys, a lost seed phrase with no backup means permanent loss of access, as the SEC's investor office notes. Coins held at an exchange are different: the account can usually be recovered through the exchange itself. Anyone offering to recover a self-custody wallet for a fee, without your backup, is very likely running a scam.
A common mistake: “Lost bitcoin can be recovered by the network or by a specialist.”
In fact: Nobody can recreate a missing private key. Words in the wrong order or a misremembered passphrase can sometimes be worked out from what you still have; a phrase lost with no backup and no fragments cannot be recovered by anybody.
How it works
Coins are locked to keys, and moving them needs a valid signature from the matching private key. bitcoin.org's FAQ says lost bitcoins remain in the blockchain like any others but stay dormant forever, because there is no way for anybody to find the private keys that would allow them to be spent again; losing a wallet has the effect of removing money from circulation. The supply count does not change. A coin that has not moved for years looks the same on chain whether it is lost or simply held, so any count of lost coins is an estimate.
