Cryptoine

Cryptoine operated as a cryptocurrency exchange, primarily facilitating the trading of Bitcoin, Litecoin, and Dogecoin. It provided a trading engine that matched buy and sell orders for these digital assets. Its headquarters is located in the United States of America. Its core service was to enable conversion between fiat or other cryptocurrencies and the listed tokens.

The exchange maintained a reserve split with 60% of assets in hot wallets and 40% in cold wallets. This ratio was disclosed following the 2015 incident. The platform committed to redistribute remaining assets according to this hot‑cold wallet split.

Cryptoine’s trading engine was noted to contain a race condition vulnerability that was exploited in March 2015, allowing an attacker to manipulate balances and drain multiple cryptocurrency holdings over seven hours. The exchange publicly asserted that the incident did not involve a system breach, private key compromise, or leakage of personal data, attributing the loss solely to the software flaw. Its response included a commitment to redistribute remaining assets according to its disclosed hot‑cold wallet ratio and to pursue a temporary hiatus while implementing security improvements.

The prompt does not provide details on Cryptoine’s ownership, parent company, or subsidiary structure. The organization is identified by the alias Cryptoine. After the incident, the exchange announced a temporary closure with the intention to resume operations once the identified vulnerabilities were addressed.

The incident was reported by news outlets such as ZDNet. The exchange indicated it would implement security improvements before considering a return to service. No further public updates on the exchange’s operations are provided in the source material.
