Former Bitcoin exchanges

FTX Trading Ltd., trading as FTX (Futures Exchange), is a bankrupt company that formerly operated a cryptocurrency exchange and crypto hedge fund. The exchange was founded in 2019 by Sam Bankman-Fried and Gary Wang and collapsed in 2022 after massive fraud perpetrated by Bankman-Fried and his partner Caroline Ellison forced the company to file for Chapter 11 bankruptcy.

BTC-e was a cryptocurrency exchange primarily serving the Russian market, with servers located in the United States. The U.S. government seized their website and funds in 2017. It was founded in July 2011 by Alexander Vinnik and Aleksandr Bilyuchenko, and as of February 2015 handled around 3% of all Bitcoin exchange volume. The platform was eventually taken over by Russian Orthodox oligarch Konstantin Malofeev, and funds from BTC-e were used for the war in Donbas, under the control of the FSB.
