Is it possible for Coinbase to seize my cryptocurrency?

Yes, it is possible for Coinbase to seize cryptocurrency from an account under certain conditions. As a centralized exchange, Coinbase operates in compliance with the laws and regulations of the jurisdictions in which it does business. This means that if an account is suspected of engaging in illicit activities, violating terms of service, or if required by a legal order such as a court-mandated seizure or subpoena, Coinbase has the authority and obligation to freeze or seize assets on their platform. Moreover, failure to adhere to Coinbase's own policies could lead to an account being restricted or closed, potentially affecting access to one’s cryptocurrency holdings. Therefore, users are advised to familiarize themselves with Coinbase's user agreement and ensure that their activities are in full compliance with all applicable laws and regulations.
