Bitcoin Cash (BCH) is set to undergo a significant network hard fork event in 2025—an upgrade that could split the blockchain into two separate chains. With major implications for traders, investors, and platforms alike, understanding how exchanges handle such events is crucial. This article explores the mechanics of the upcoming BCH fork, outlines key actions users should take, and explains how leading platforms manage asset distribution, trading suspensions, and risk controls during these volatile periods.
Understanding the Bitcoin Cash Hard Fork
A hard fork occurs when a blockchain’s protocol is updated in a way that isn’t backward-compatible, resulting in a permanent divergence from the previous version. In the case of Bitcoin Cash, the 2025 hard fork stems from a disagreement between development teams—primarily over consensus rules and network upgrades—leading to two competing node implementations.
Holders of BCH before the fork may receive two distinct assets: the original chain's continuation and a newly formed token from the alternative chain. While both chains share the same transaction history up to the split point, they operate independently afterward.

Exchange Response: Trading and Service Adjustments
To maintain platform stability and protect user interests, digital asset exchanges typically implement a series of operational changes ahead of a hard fork.
Suspension of Margin and Spot Trading
Prior to the fork, exchanges often disable certain services to mitigate technical and financial risks:
- BCH margin borrowing is suspended several days before the fork.
- Users with open margin positions must repay borrowed funds before a forced liquidation deadline.
- Spot and margin trading pairs involving BCH are paused approximately 24 hours before the expected fork time.
- Deposits and withdrawals are temporarily halted to allow accurate snapshotting of user balances.
These measures ensure orderly operations during network uncertainty and prevent issues like double-spending or balance discrepancies.
Derivatives Market Adjustments
Futures and perpetual contracts require special handling due to their reliance on real-time price indices.
Contract Underlying Asset Selection
Before the fork, BCHUSD and BCHUSDT contracts track the original Bitcoin Cash price. During and after the split, exchanges use a multi-source index composed of major trading platforms (e.g., Binance, Huobi, Coinbase, OKX) to determine which chain becomes the primary reference.
The selection criteria typically favor:
- The chain with higher market liquidity
- The chain listed on more exchanges
- The chain showing stronger price stability and trading volume
Post-fork, the contract continues tracking the dominant chain under the same ticker symbol (e.g., BCHUSD), while the minority chain may be listed separately if it gains traction.
Risk Management During Volatility
During the transition period—especially when spot markets are offline—exchanges adjust risk parameters:
- Price limits are expanded using formulas based on recent candlestick averages.
- Liquidation triggers shift from mark price to mid-market price:
(Best Bid + Best Ask) / 2 - Funding rates for perpetual contracts may be capped at zero to prevent unfair accruals during illiquid phases.
These temporary rules help prevent cascading liquidations and maintain fair market conditions.

Financial Services and Lending Protocols
Platforms offering yield-generating products also adapt their systems:
- Savings programs (e.g., "Flexible Savings" or "Yield Accounts") continue accruing interest post-fork, with rewards distributed based on supported chains.
- Collateralized loans using BCH as collateral are frozen before the fork.
- Borrowers must repay loans before a mandatory redemption window; otherwise, automatic liquidation occurs.
This ensures loan-to-value ratios remain valid across both chains and prevents systemic risks in lending pools.
Fork Asset Distribution Process
One of the most anticipated aspects of any hard fork is receiving new tokens. Here’s how it generally works:
- Balance Snapshot:
A 5-minute snapshot captures all user holdings at a predefined block height or timestamp (e.g., November 15, 2025, 21:00–21:05 HKT). Token Allocation:
- The chain deemed more dominant retains the BCH ticker.
- The secondary chain is distributed as a new asset via 1:1 airdrop to users’ funding accounts.
- Accessing New Assets:
Users can view both assets under “Assets > My Assets > Funding Account.” Deposits, withdrawals, and trading for the new token resume once sufficient exchange support exists.

Frequently Asked Questions
Q: What happens to my BCH during a hard fork?
A: If you hold BCH in your exchange account before the snapshot time, you’ll retain your original holdings and likely receive an equivalent amount of a new token from the alternative chain.
Q: Do I need to move my BCH to receive forked tokens?
A: No. As long as your BCH is in your account before the snapshot, the exchange will automatically credit any new tokens. There’s no action required on your part.
Q: Which chain will keep the BCH symbol?
A: Exchanges typically assign the BCH ticker to the chain with greater market consensus—measured by liquidity, exchange listings, and trading volume.
Q: Can I trade both chains after the fork?
A: Yes, but not immediately. Once markets stabilize and deposit/withdrawal functions resume, exchanges list the secondary token under a new name (e.g., BCHA or BCHN).
Q: Why are futures contracts not settled during the fork?
A: To avoid settlement inaccuracies due to missing spot prices. New weekly or bi-weekly contracts are paused until reliable pricing data returns.
Q: Are hard forks taxable events?
A: In some jurisdictions, receiving new tokens may be considered taxable income. Consult a tax professional for guidance based on your region.
Final Thoughts: Stay Informed, Stay Protected
Hard forks like the 2025 Bitcoin Cash upgrade represent both opportunities and risks. While they can yield free tokens, they also introduce market volatility, technical disruptions, and potential security threats like replay attacks.
Always rely on official exchange announcements—not social media rumors—and avoid sending funds unnecessarily. Reputable platforms like OKX handle the entire process transparently, ensuring user assets remain secure throughout the transition.
