Gemini is a centralized cryptocurrency platform founded in 2014 by Cameron and Tyler Winklevoss. It provides account-based trading and custody services for individuals and institutions. Assets held through an exchange account remain within the provider’s custody system until they are withdrawn to an external address.

Account access and trading

Gemini customers use a verified account to access the products available in their jurisdiction. The platform supports exchange trading and publishes current asset and market information, but the exact pairs and features can differ by region and customer type.

An exchange account is custodial

Account credentials control access to Gemini’s service, while Gemini operates the custody infrastructure. Moving assets to a self-custody wallet requires an on-chain withdrawal.

Custody and reserves

Gemini describes itself as a full-reserve exchange and custodian. Its trust center says customer digital assets are held separately from company assets and are available for withdrawal. This is still a custodial arrangement: the service controls the operational keys and account systems.

Availability depends on location

Gemini publishes an availability page for supported countries and U.S. states. Readers should check it directly because the company announced 2026 wind-downs in the United Kingdom, the European Economic Area, Australia, and other markets. A feature visible in one region may be unavailable in another.

Check regional status before relying on a feature

Supported products and even account availability can change with local regulation and company decisions. Current provider notices are more reliable than an older review or comparison table.
