Vircurex (vircurex.com) — CEX (centralized exchange)

Vircurex was an early centralized cryptocurrency exchange that opened for trading in October 2011, offering markets in Bitcoin and several early altcoins, alongside more advanced, exchange-run features (for its era) such as stop orders, options, and loans. (en.bitcoin.it)

What it was known for

• Altcoin access in the early days: It listed multiple “popular alt chains” at a time when exchange options were limited. (en.bitcoin.it)
• Custodial (CEX) model: Users deposited funds and traded on the platform, i.e., it operated as a typical centralized exchange rather than an on-chain DEX. (en.bitcoin.it)
• Fiat rails (historical): Bitcoin Wiki notes USD/EUR funding methods used at the time (e.g., Liberty Reserve), reflecting the exchange’s early attempt at bridging crypto and legacy payment systems. (en.bitcoin.it)

What happened / current status

• Withdrawals were frozen amid hacks and financial distress: Reporting from March 24, 2014 describes Vircurex freezing withdrawals after prior hack-related losses and depleted reserves. (slashgear.com)
• Service discontinued: Bitcoin Wiki now carries an explicit warning that the exchange has discontinued its services, and that any later domain acquisition would not represent the original operators. (en.bitcoin.it)
• Legal dispute (allegations): A class-action complaint filed January 10, 2018 (U.S. District Court, Colorado) alleged that customers had “frozen” funds on the exchange and described claimed operator relationships; these are allegations in litigation, not an adjudicated finding in that document itself.

In short: Vircurex is best understood today as a historically notable but defunct CEX brand, frequently cited in “not your keys, not your coins” cautionary lore from the early exchange era. (en.bitcoin.it)
