Bitcoin-24

Bitcoin-24 was an early cryptocurrency exchange, once touted as one of Europe’s largest venues for buying and selling Bitcoin. It was founded on May 1, 2012, and operated with European (EUR) and USD trading options, including methods like bank transfers and credit cards. Over the years it faced regulatory and security troubles, most notably a 2013 period during which German bank accounts were seized and withdrawals were disrupted; authorities later lifted the seizure, but the exchange ultimately did not resume normal operations and is now considered closed.
