Bitfinex


Bitfinex

The largest Bitcoin exchange as of the end of 2017 with some 12% of the Bitcoin market. In 2016, a hack stole USD $72M from random wallets. In response, Bitfinex reduced their customers' wallet holdings by 36% to distribute the loss among all users along with tokens to compensate for those losses. The tokens were later bought back for $1 each. See Bitcoin.
