A “delisted coin” means that a particular cryptocurrency has been removed from a trading exchange’s listing, so you can no longer buy, sell, or trade that coin on that specific platform.
What delisting actually meansThe coin’s trading pairs (like BTC/XYZ, USDT/XYZ) are deleted from the exchange. The project may still exist and trade elsewhere (other exchanges, DEXs, or OTC), but access and liquidity on that exchange dry up.

Why coins get delistedCommon reasons include:Very low trading volume or liquidity. Failing regulatory/compliance requirements or project‑related scandals/fraud concerns. The project team or exchange decides to remove it for risk control, maintenance cost, or quality standards.
What usually happens to your coinsExchanges usually allow a withdrawal window after delisting so you can move the coins to another wallet or exchange.$A2Z

If you don’t act, some platforms may auto‑convert them to a stablecoin or stop supporting them, risking loss of access. $DENT

In short: a delisted coin is gone from that exchange, but you should check your holdings and either withdraw or swap before the deadline.
