The impending Bitcoin Cash (BCH) hard fork in November 2018 sparked significant activity across major cryptocurrency exchanges. As the network approached a critical upgrade at Unix time 1542300000 — corresponding to November 16, 2018, at 00:40 Singapore Time — platforms worldwide adjusted their services to ensure user safety, maintain operational stability, and prepare for potential chain splits. This article details how leading exchanges responded to the event, including updates on deposit and withdrawal suspensions, snapshot procedures, contract settlements, and token distribution plans.
Exchange Responses to the BCH Hard Fork
Huobi Global: Delayed Suspension of BCH Deposits and Withdrawals
In response to user demand, Huobi Global postponed its original schedule and announced it would suspend Bitcoin Cash deposits and withdrawals at 21:00 on November 15, 2018 (Singapore Time). The exchange conducted a full asset snapshot at the moment of the hard fork — 00:40 on November 16 — across all user accounts, including spot trading, margin, and wallet balances.
Huobi emphasized that a successful fork must meet two key criteria:
- Implementation of strict two-way replay attack protection.
- Independent and stable block production on both resulting chains.
If both Bitcoin SV (BSV) and Bitcoin ABC chains operate independently with proper safeguards, Huobi committed to distributing forked tokens to users at a 1:1 ratio, based on verified snapshots. Eligible accounts included:
- Spot accounts: Distribution based on BCH holdings at snapshot time.
- HB10 index fund holders: Rewards allocated proportionally according to BCH weighting in the basket.
- Margin accounts: Snapshot amount calculated after deducting any borrowed but unpaid BCH.
Notably, balances under 0.001 BCH were excluded from the snapshot, while funds locked in open orders were included.

Binance: System Maintenance Completed Ahead of Schedule
Binance successfully concluded its scheduled system maintenance earlier than expected. Trading resumed at 17:00 UTC+8, allowing users to place trades, withdraw, or deposit assets following a brief service interruption. The early completion minimized downtime during a volatile period leading up to the BCH fork, ensuring traders could react swiftly to market movements.
OKEx: Early Settlement of BCH Futures Contracts
Due to heightened price volatility caused by uncertainty around the BCH hard fork, OKEx decided to prematurely settle all BCH futures contracts on November 14, 2018. This move aimed to protect users from extreme fluctuations and potential manipulation during the split.
Affected contracts included:
- BCH Weekly (1116)
- BCH Bi-weekly (1123)
- BCH Quarterly (1228)
Key timeline:
- Trading halt: 16:05 HKT — No new orders accepted.
- Final price determination: Based on the last traded price at 16:05 HKT per contract.
- Settlement execution: At 17:00 HKT, using finalized prices, followed by standard risk reserve deductions and loss-sharing mechanisms.
OKEx reserved the right to adjust the settlement price if evidence of market manipulation emerged, ensuring fairness in volatile conditions.
DigiFinex: Support for BCH Chain Split
DigiFinex confirmed support for the BCH hard fork. The platform suspended BCH deposits and withdrawals at 23:00 GMT+8 on November 15, then took a comprehensive user balance snapshot just before the fork at 23:59:59 GMT+8. This ensured accurate record-keeping for potential airdrops of newly created tokens.
Bitfinex: Introduction of Chain Split Tokens (CST)
To give users flexibility and exposure to both potential outcomes of the split, Bitfinex introduced Chain Split Tokens (CST). These tokens represented claims on either:
- BAB: Tokens from the Bitcoin ABC chain.
- BSV: Tokens from the Bitcoin SV chain.
Trading pairs launched included BAB/USD, BAB/BTC, BSV/USD, and BSV/BTC, enabling traders to speculate or hedge before the actual chain resolution. This innovative approach allowed Bitfinex to avoid premature endorsement of one chain while offering liquidity for both factions.

Frequently Asked Questions (FAQ)
Q: What is a blockchain hard fork?
A: A hard fork is a permanent divergence in a blockchain’s protocol that creates two separate chains — one following the old rules and one under new ones. In the case of BCH, this resulted in potential new tokens like BSV and BAB.
Q: Why did exchanges stop BCH deposits before the fork?
A: Halting deposits prevents transaction conflicts during chain splits. Without this pause, users might lose funds due to replay attacks or misdirected transfers across incompatible chains.
Q: How were forked tokens distributed?
A: Exchanges used snapshots to record user balances before the fork. Eligible holders received new tokens (e.g., BSV or BAB) in proportion to their original BCH holdings, typically at a 1:1 ratio.
Q: What is replay protection?
A: Replay protection prevents transactions on one chain from being duplicated on another after a fork. Two-way protection ensures security for both networks, which many exchanges required before recognizing a successful split.
Q: Could I lose money during a crypto fork?
A: While holding through a fork generally preserves value across both chains, risks include price volatility, exchange delays in supporting new tokens, and potential scams impersonating legitimate airdrops.
