An exit scam in cryptocurrency is a deliberate fraud where a project's operators raise capital from investors — through an ICO, private sale, NFT mint, exchange operation, or other mechanism — and then abruptly disappear with the funds, abandoning the project and ceasing all communication. Exit scams differ from rug pulls (which typically exploit smart contract mechanics) in that they often involve longer-running projects that build genuine trust before executing the fraud. HOW EXIT SCAMS DIFFER FROM RUG PULLS Rug Pull: Usually happens within hours to days of launch. Smart contract-based extraction of liquidity. Often anonymous from inception. Exit Scam: Can involve projects running for months or years. May have real products, active communities, and credible teams. The fraud is the planned intention to eventually steal funds — the operational period is the setup. NOTORIOUS CRYPTO EXIT SCAMS Thodex (2021): Turkish crypto exchange with 400,000 users. CEO Faruk Fatih Özer fled Turkey with an estimated $2B in customer funds. The exchange suddenly halted trading. Özer was eventually extradited from Albania and sentenced to 11,000 years in prison. OneCoin (2014-2019): Bulgarian crypto promoted as a Bitcoin competitor via MLM. Raised $4.4B globally including heavily in India and Southeast Asia. No actual blockchain ever existed. Founder Ruja Ignatova ("Crypto Queen") disappeared in 2017 and remains one of FBI's most-wanted fugitives. BitConnect (2016-2018): Lending platform promising 1% daily returns. Collapsed in January 2018 after regulatory warnings. Estimated $2.5B in losses. Several promoters prosecuted. Gerald Cotton / QuadrigaCX (2018): Canadian exchange founder died mysteriously with sole knowledge of cold wallet passwords. $190M in customer funds inaccessible. Circumstances remain disputed. WARNING SIGNS OF POTENTIAL EXIT SCAMS Unrealistic return promises (guaranteed 1% daily). Heavy MLM recruitment structure. Centralised control of all customer funds with no audits. Founder identity not independently verifiable. Registered in opaque jurisdictions. "We're saving your funds for you" narrative — preventing withdrawals. INDIA CONTEXT India has been disproportionately targeted by exit scam operators due to large retail crypto interest and regulatory gaps. OneCoin, BitConnect, GainBitcoin, and numerous smaller schemes have defrauded Indian investors of billions in total.
