Exmo is a cryptocurrency exchange with its headquarters based in Estonia. One significant aspect to note is that Exmo is not a regulated cryptocurrency exchange, which means it does not operate under the oversight of regulatory authorities. This lack of regulation can impact the level of security and consumer protection provided by the exchange. Users have raised concerns about the fulfillment of deposit and withdrawal requests, as well as frequent downtimes experienced on the platform. Additionally, there was a highly publicized incident involving the kidnapping of Exmo's Managing Director, Pavel Lerner, which reportedly involved a ransom payment in Bitcoin for his release.
