Chain Split Tokens (CSTs) are the first such product of its kind, allowing Bitfinex customers to speculate on future fork events of the Bitcoin blockchain, specifically, the potential fork between Bitcoin Core and Bitcoin Unlimited by 11:59:59 UTC December 31, 2017. CSTs are designated as BCC (Bitcoin Core) and BCU (Bitcoin Unlimited). CSTs trade as BTC and USD pairs.
Users will be able to create CSTs by “splitting” a bitcoin through the Token Manager (located in the Order Form’s Order Type drop-down menu in the sidebar). Once split, the BTC will be removed from your account for each BCC and BCU added. Through the same Token Manager, you will be able to reverse this process at any time, trading in equal numbers of BCC and BCU to extract BTC.
