Bitcoin Cash (BCH) is approaching a critical moment in its network evolution. On November 15, a scheduled protocol upgrade — commonly referred to as a fork — could potentially split the blockchain into two incompatible chains. Unlike routine upgrades, this one carries significant uncertainty and risk due to the emergence of two competing software versions: Bitcoin ABC 0.18.2 and Bitcoin SV (Satoshi Vision).
If neither side reaches consensus within the next 10 days, the result will be a hard fork, leading to the creation of two separate cryptocurrencies under the BCH name. This development raises serious concerns about network security, mining centralization, and long-term viability.
Understanding the BCH Fork: Two Competing Visions
At the heart of the upcoming split are two divergent philosophies on how Bitcoin Cash should evolve.
The Bitcoin ABC 0.18.2 client, backed by major industry players including Bitmain, aims to maintain and expand upon the current direction of Bitcoin Cash — focusing on peer-to-peer electronic cash with moderate block size increases and improved transaction processing. It represents the more widely adopted vision within the existing BCH ecosystem.
On the other hand, Bitcoin SV (Satoshi’s Vision) advocates for a return to what its supporters believe was the original intent of Bitcoin: massive on-chain scaling, unlimited block sizes, and enterprise-level data storage capabilities. The BSV client, version 0.1, is primarily supported by mining pools such as SVPool and CoinGeek, which together control approximately 3,000 petahashes (PH/s) — around 5% of the total SHA-256 mining power.

Without reconciliation between these factions, the network will fragment — not just technically, but economically and ideologically.
Market Implications: Will Value Be Created or Diluted?
A common misconception during forks is that new coins automatically generate additional value. In reality, value does not appear out of thin air. When a blockchain splits, the market must decide how to allocate value between the resulting assets.
If both chains survive post-fork — let’s call them BCH (ABC) and BCH (SV) — their combined market capitalization is unlikely to exceed the pre-fork value of Bitcoin Cash. Instead, investors and miners will weigh utility, security, and adoption to determine each chain's worth.
Currently, BCH trades at roughly 9% of Bitcoin’s price, up from 6.5% just days before the anticipated fork. This surge may reflect speculative interest ahead of the event. However, price alone doesn’t guarantee network resilience.
Security Risks After the Split
One of the most pressing issues following a fork is hash rate distribution. Mining power determines how secure a blockchain is against attacks like double-spending or 51% takeovers.
Before the split, Bitcoin Cash benefits from shared SHA-256 mining resources with Bitcoin. But once divided:
- Each chain will likely see a sharp drop in active hash rate.
- With less computational power protecting each network, the risk of malicious attacks increases dramatically.
- Both chains could inherit up to 56 exahashes (EH/s) of potential attack capacity from idle or rentable ASIC miners.
This last point is particularly concerning. A growing number of energy-efficient SHA-256 mining rigs — some 30% more efficient than the Antminer S9 — are entering the market. These devices can be deployed quickly and even rented on-demand through cloud mining services.
Such accessibility lowers the barrier for launching large-scale attacks on lower-hash chains. If either BCH (ABC) or BCH (SV) falls below a critical security threshold, it becomes vulnerable to manipulation by well-funded actors.

Mining Support: Who Holds the Power?
Mining support plays a pivotal role in determining which chain survives — or dominates — after a fork.
As of now:
- Bitcoin ABC 0.18.2 enjoys broader industry backing, especially from Bitmain, one of the largest manufacturers of ASIC miners. This gives it a structural advantage in attracting hash power.
- Bitcoin SV 0.1 relies heavily on SVPool and CoinGeek, which together contribute about 5% of global SHA-256 capacity. While not insignificant, this level of support may struggle to sustain an independent chain long-term without additional buy-in.
Even with strong miner alignment, maintaining network integrity post-fork requires continuous investment in protection mechanisms — including vigilant monitoring and emergency response protocols. These ongoing costs reduce profitability for miners and may discourage participation over time.
Can Both Chains Survive?
For both forks to remain viable, each would need to maintain at least 5% of Bitcoin’s market value — a benchmark that suggests sufficient user demand, exchange listings, and mining incentives.
However, sustaining this level of valuation amid declining BTC-relative prices (especially in a bear market) is uncertain. Lower prices lead to reduced mining rewards, which in turn cause miners to abandon less profitable chains.
Historically, most contentious forks result in one dominant chain absorbing the majority of value and hash power, while the minority chain either stagnates or fades into obscurity.
Given these dynamics, it’s plausible — even likely — that only one version of BCH will emerge as sustainable in the long run.
Frequently Asked Questions (FAQ)
Q: What is a blockchain fork?
A: A blockchain fork occurs when a cryptocurrency’s protocol is updated in a way that creates a divergence in the ledger. If the change isn't universally accepted, it can result in two separate chains operating independently.
Q: Will I receive free coins if BCH splits?
A: If you hold BCH in a personal wallet before the fork, you may own coins on both resulting chains — provided both are supported by your wallet provider and exchanges you use.
Q: Which BCH chain is safer to hold?
A: The chain with greater hash rate and broader exchange support will generally be more secure and liquid. Monitor official announcements from major wallets and trading platforms for guidance.
Q: Could this fork affect Bitcoin (BTC)?
A: Direct technical impact is minimal since BCH uses a separate blockchain. However, increased volatility in altcoins can sometimes spill over into broader market sentiment.
Q: How can I protect my BCH during the fork?
A: Use a non-custodial wallet where you control private keys. Avoid moving funds around the fork date until networks stabilize and replay protection is confirmed.
Q: Is this fork bullish or bearish for crypto overall?
A: While forks generate short-term attention and trading volume, prolonged uncertainty can erode confidence. Long-term effects depend on how cleanly the split resolves and whether innovation follows.
Final Thoughts: A Shadow Over Bitcoin Cash’s Future
Bitcoin Cash was born from a vision of fast, low-cost transactions — a digital cash system accessible to all. But repeated internal conflicts and technical fractures threaten that mission.
This upcoming fork isn’t just a software update; it’s a test of governance, economic sustainability, and community cohesion. The presence of high-efficiency mining hardware and rentable hash power further complicates matters, increasing systemic risks across both potential chains.
While Bitcoin ABC currently appears better positioned due to wider support, no outcome is guaranteed. Investors, developers, and users alike must prepare for volatility, security threats, and possible fragmentation.
