The cryptocurrency market witnessed extraordinary volatility in mid-November 2017, as Bitcoin staged a dramatic recovery from a weekend crash below $5,500 to surge past $7,900 — coming within striking distance of the $8,000 milestone. The rally added roughly $41 billion to Bitcoin’s market capitalization in under a week, bringing it to approximately $133.5 billion.
TL;DR
- Bitcoin surged ~45% from its weekend low near $5,500 to touch $7,998.40
- The rally was fueled by the cancelation of the controversial SegWit2x hard fork
- Bitcoin’s market cap climbed from $92 billion to $133.5 billion in approximately six days
- Bitcoin Cash dropped 14.6% while XRP gained 17.6% on the day
- $262 million was traded on Kraken alone across all markets on November 16
SegWit2x Cancelation Becomes the Catalyst
The dramatic price action can be traced directly to the fate of the SegWit2x upgrade — a proposed hard fork that would have doubled Bitcoin’s block size to 2MB in an effort to increase transaction throughput. Originally scheduled for implementation on November 16, the upgrade had been a source of deep division within the Bitcoin community for months.
On November 8, the organizers of the SegWit2x effort announced they were suspending their plans, citing a lack of consensus. The initial market reaction was sharp and negative: Bitcoin sold off heavily over the weekend, briefly dipping to around $5,500 as traders digested the implications and uncertainty swirled.
However, as the dust settled, the narrative flipped dramatically. The removal of the fork uncertainty eliminated a major overhang that had weighed on Bitcoin’s price. What initially looked like a sell-the-news event quickly transformed into a buy-the-dip opportunity of historic proportions.
A Remarkable Recovery
From its Sunday low near $5,500, Bitcoin embarked on a relentless rally that would see it climb approximately 45% in just six days. By November 16, the cryptocurrency was trading around $7,871, according to CoinMarketCap data. In the early hours of November 17 (UK time), Bitcoin touched an all-time high of $7,998.40 — less than $2 away from the psychologically significant $8,000 level.
The sheer speed of the recovery was breathtaking. In dollar terms, Bitcoin added approximately $41 billion to its market capitalization during this six-day stretch, with total market cap rising from roughly $92 billion to $133.5 billion.
The trading volume reflected the intensity of market activity. Kraken, one of the major cryptocurrency exchanges, reported $262 million traded across all its markets on November 16 alone, spanning crypto pairs against EUR, USD, JPY, CAD, and GBP.
Remnants of Fork Risk Linger
Despite the official cancelation, some uncertainty lingered. Coinbase, one of the world’s largest cryptocurrency exchanges, issued a statement on November 17 noting that a small number of miners might still attempt to execute the SegWit2x fork. This kept markets somewhat on edge, though the overwhelming consensus was that the fork threat had been neutralized.
The year 2017 had already seen two successful Bitcoin forks that created new cryptocurrencies: Bitcoin Cash in August and Bitcoin Gold in October. Each fork had introduced volatility and uncertainty, but also generated significant interest from investors looking to claim their “free” forked coins.
Mainstream Validation Continues
The Bitcoin rally was further supported by growing mainstream acceptance. On October 31, CME Group — the world’s largest derivatives marketplace — announced plans to launch Bitcoin futures in the fourth quarter of 2017, a move designed to “professionalize” the crypto asset class and give institutional investors regulated access to Bitcoin exposure.
The announcement had already sent Bitcoin to new highs in early November, and the momentum carried through the SegWit2x episode. Morgan Stanley’s CEO James Gorman publicly stated that Bitcoin was “not a fad,” adding to the growing chorus of mainstream financial figures acknowledging cryptocurrency’s staying power.
Why This Matters
The events of November 16, 2017, represent a pivotal moment in Bitcoin’s history. The SegWit2x saga tested the resilience of Bitcoin’s governance model and, ultimately, demonstrated the strength of its decentralized decision-making process. The fact that Bitcoin emerged from a bitter scaling debate with a 45% rally to near $8,000 sent a powerful signal about the market’s confidence in the original Bitcoin blockchain.
The upcoming CME futures launch, combined with the removal of fork uncertainty, set the stage for Bitcoin’s historic run toward $10,000 and eventually $20,000 in December 2017. This period marked the transition of Bitcoin from a niche technology experiment to a globally recognized financial asset.

Garzik must have felt the entire room turn on him in real time. the NY Agreement signatories bailed one by one and left him holding the bag
1MB vs 2MB seems quaint now with ordinals clogging blocks. the block size warriors were fighting the wrong battle entirely
the irony of 1MB warriors winning the debate and now ordinals fill blocks anyway. nature finds a way
the block size debate split communities apart. losing friends over 1MB vs 2MB sounds absurd now but it was intense back then
imagine the anxiety of holding through that $5,500 weekend crash. weak hands got cleared before the real move
Halima J. the weekend crash flushed out so many leveraged longs. the bounce back was almost guaranteed once that overhang cleared
the block size debate was never about 1MB vs 2MB. it was about who controlled the reference implementation and development roadmap. everything else was theater
SegWit2x cancellation was the best outcome. The block size debate was tearing the community apart.
Market cap added $41B in a week – shows how much uncertainty was priced in before the cancelation.
