KeepChange

KeepChange operates as a cryptocurrency exchange platform that enables users to trade digital assets and request withdrawals, with a particular focus on bitcoin transactions. The company is headquartered in the United States of America, positioning it within a major financial and technology hub. As an exchange, it provides a marketplace where individuals can buy, sell, and hold various cryptocurrencies, relying on its infrastructure to facilitate order matching and settlement. KeepChange emphasizes the security of asset transfers, implementing internal controls designed to prevent unauthorized movement of funds. The platform’s services are intended for retail and possibly institutional participants seeking to engage with the crypto market through a user‑friendly interface.

In February 2021, KeepChange experienced a security breach in which attackers gained access to its systems and attempted to initiate fraudulent bitcoin withdrawals. Although the exchange’s transfer‑blocking mechanisms stopped all illicit fund movements, preventing any cryptocurrency loss, the intruders exfiltrated sensitive user data including names, email addresses, password hashes, trade history counts, and aggregated transaction values. This incident highlighted a disparity between the effectiveness of its asset‑protection controls and the vulnerability of its data‑storage safeguards. The breach underscored the importance of comprehensive security measures that address both financial and personal information risks. Despite the compromise, KeepChange continued to operate as an exchange, maintaining its commitment to securing transaction flows for its users.
