TL;DR
- The SegWit2x hard fork was officially cancelled on November 8, 2017, after failing to achieve sufficient community consensus
- Bitcoin’s price crashed nearly 29% from its all-time high of $7,882 to approximately $5,605 before staging a recovery to around $6,559
- Bitcoin Cash surged over 130% in just 48 hours, briefly overtaking Ethereum to become the second-largest cryptocurrency by market cap
- The collapse of SegWit2x raises fundamental questions about governance, decision-making, and regulatory oversight in decentralized networks
- Former Fortress executive Mike Novogratz declared that “big money is coming to bitcoin,” signaling growing institutional interest despite the turmoil
The cryptocurrency world is witnessing one of its most significant governance crises to date. The cancellation of the SegWit2x hard fork, originally scheduled for November 16, 2017, has sent shockwaves through digital asset markets and ignited a fierce debate about how decentralized networks should be governed — and whether regulators will eventually step in to impose order on what has proven to be a deeply fractured community.
The SegWit2x Debacle: What Happened
SegWit2x was conceived as part of the New York Agreement, a compromise reached in May 2017 between Bitcoin miners and businesses. The proposal aimed to increase Bitcoin’s block size from 1MB to 2MB, effectively doubling transaction capacity. It was seen as a moderate solution to Bitcoin’s persistent scalability problem — a middle ground between the “big block” faction that wanted larger blocks and the “small block” camp that favored off-chain solutions like the Lightning Network.
But on November 8, Mike Belshe, CEO of BitGo and one of the plan’s key organizers, sent an email announcing the suspension of the fork. The reason was straightforward: there simply wasn’t enough consensus. “Although we strongly believe in the need for a larger block size, there is something we believe is even more important: preserving the integrity of the Bitcoin ecosystem,” Belshe wrote. The organizers concluded that forcing a fork would “divide the community and be a setback to Bitcoin’s growth.”
The cancellation sent immediate tremors through the market. Bitcoin, which had just reached an all-time high of $7,882 on November 8, began a precipitous decline. By November 12, the price had plummeted roughly 29% to approximately $5,605 — the largest single correction in Bitcoin’s history at that point. The total market capitalization shed billions of dollars in a matter of days.
Bitcoin Cash Emerges as the Unexpected Winner
While Bitcoin reeled from the SegWit2x fallout, Bitcoin Cash (BCH) experienced a dramatic surge. Created just three months earlier through an August hard fork, BCH saw its price skyrocket more than 130% in just 48 hours. At its peak on November 12, BCH reached an all-time high of $2,477.65, and its market capitalization briefly surpassed Ethereum’s, making it the second most valuable cryptocurrency.
Perhaps even more significantly, Bitcoin Cash’s hashrate — the total computational power securing its network — actually surpassed Bitcoin’s for a brief period on November 12. This was an extraordinary development for a cryptocurrency that many had dismissed as a footnote just months earlier. According to analyst Willy Woo, Bitcoin Cash had become heavily backed by Chinese traders and miners, making it what he described as a “strategic and geopolitical bet” on Chinese influence in the crypto space.
However, the BCH rally proved to be short-lived. On November 13, Bitcoin Cash crashed dramatically, losing roughly half its value and falling from its all-time high to around $1,277, before settling near $1,354 according to CoinMarketCap data.
The Governance Question No One Can Answer
The SegWit2x episode has laid bare a fundamental tension at the heart of cryptocurrency: how should a decentralized, trustless system make collective decisions? Bitcoin has no CEO, no board of directors, and no regulatory framework governing its protocol changes. Decisions are made through a loosely defined process of community consensus that, as the SegWit2x failure demonstrates, can break down entirely.
The block size debate, which has raged for years, perfectly encapsulates this problem. One faction argues that larger blocks make transactions cheaper and faster for users, moving Bitcoin closer to its original vision as peer-to-peer electronic cash. Their opponents counter that bigger blocks make mining more resource-intensive, potentially centralizing power among large mining operations and undermining Bitcoin’s core decentralization principle.
This governance vacuum has regulatory implications that extend far beyond the crypto community. As digital assets attract increasing institutional attention — CME Group announced plans to launch Bitcoin futures by year-end, and Japan has legalized Bitcoin as a method of payment — regulators worldwide are watching closely. The inability of the Bitcoin community to resolve its internal disputes through consensus mechanisms may ultimately invite the kind of external regulatory intervention that cryptocurrency was designed to avoid.
Mike Novogratz: Big Money Is Coming
Amid the chaos, former Fortress Investment Group executive Mike Novogratz offered a bullish counter-narrative. Speaking on November 13, Novogratz declared that “big money is coming to bitcoin,” arguing that institutional investors were increasingly viewing cryptocurrency as a legitimate asset class regardless of short-term volatility.
Novogratz’s timing was notable. Bitcoin was in the middle of a dramatic recovery, surging more than 11% in just 12 hours on November 13 to trade around $6,520, adding over $10 billion to its market capitalization in a single session. The recovery suggested that despite the governance turmoil, demand for Bitcoin remained robust — a signal that the market viewed the SegWit2x cancellation as a short-term disruption rather than a fundamental flaw.
Market Recovery and What It Means
By the close of November 13, Bitcoin was trading at approximately $6,559, according to CoinMarketCap data, with a market capitalization of $109.4 billion. Ethereum held steady at $316.72, and the broader cryptocurrency market showed signs of stabilizing after a wild weekend of trading.
The speed of the recovery is itself significant. While Bitcoin’s governance mechanisms may be imperfect, the market’s ability to absorb and recover from a 29% crash in less than a week suggests a level of resilience that should not be underestimated. Whether this resilience will be sufficient to withstand future governance crises — and whether regulators will allow the crypto community to continue resolving its disputes internally — remains an open question.
Why This Matters
The SegWit2x cancellation is not just a technical event. It is a case study in the challenges of decentralized governance and a preview of the regulatory battles to come. As cryptocurrency moves from the fringes of finance into the mainstream, the inability of digital asset communities to resolve internal disputes through consensus will increasingly become a regulatory concern. The Bitcoin community’s challenge is not just technical scalability — it is governance scalability. And on that front, the events of November 2017 suggest there is still a very long way to go.
