HodlHodl is a KYC service; they collect your location, your IP address, and all your browser metadata, and store this information for the number of years required by law. In the event of a dispute, they can freeze your funds and ask you for your ID; they may also suspect you of money laundering or fraud and freeze your funds. Non-KYC services include Robosats and Bisq. There is nothing in the world that pisses me off more than lies.
