The cryptocurrency world experienced another dramatic split on October 24, 2017, as the Bitcoin blockchain underwent its second major hard fork in three months. The result was Bitcoin Gold (BTG), a new digital currency designed to make mining more accessible. But within hours of its creation, the fledgling cryptocurrency had already lost two-thirds of its value, raising serious questions about the growing trend of forking Bitcoin to create competing chains.
TL;DR
- Bitcoin Gold hard fork occurred on October 24 at block 491,407, creating a new cryptocurrency
- BTG plunged 66% from approximately $539 to around $161 within hours of launch
- Bitcoin itself dipped to $5,374 before recovering to trade near $5,900 on October 26
- The BTG website suffered a DDoS attack, and major exchanges had not yet opened trading
- Altcoins like Ethereum, Ripple, and Litecoin declined as capital flowed into BTC ahead of the fork
What Is Bitcoin Gold and Why Does It Matter?
Bitcoin Gold was the brainchild of Jack Liao, CEO of LightningASIC, a company that sells mining equipment. The core idea behind the fork was to change Bitcoin’s mining algorithm so that everyday users with standard graphics processing units (GPUs) could participate in mining, rather than the process being dominated by entities with expensive specialized hardware known as ASIC miners.
The fork occurred at block 491,407 on the Bitcoin blockchain, effectively creating a duplicate of Bitcoin’s transaction history up to that point. Every Bitcoin holder at the time of the snapshot received an equivalent amount of Bitcoin Gold at a one-to-one ratio. However, unlike the Bitcoin Cash fork in July, Bitcoin Gold’s launch came with an unusual twist: the development team pre-mined approximately 100,000 BTG coins before releasing the software to the public, a move that drew criticism from across the cryptocurrency community.
A Rocky Launch for the New Cryptocurrency
The hours following Bitcoin Gold’s debut were anything but smooth. The new cryptocurrency’s official website was hit with a distributed denial-of-service (DDoS) attack, preventing users from accessing critical information and resources. Most major cryptocurrency exchanges, including some of the largest platforms in the world, had not yet begun trading Bitcoin Gold, limiting its market exposure to smaller futures markets.
On these early markets, Bitcoin Gold was initially valued at approximately 0.047 BTC, roughly $270 at the time. But the price quickly unraveled. From its all-time high of around $539 reached on October 23, BTG plummeted over 66%, trading at just above $161 per coin by October 25. The sell-off appeared driven by holders immediately dumping their newly-acquired coins, signaling a lack of confidence in the project’s long-term viability.
Bitcoin Weather the Storm While Altcoins Bleed
Despite the turbulence surrounding the fork, Bitcoin itself demonstrated remarkable resilience. After hitting a low of $5,374.60 on October 25, BTC recovered nearly $300 within hours. By October 26, Bitcoin was trading at approximately $5,904, according to CoinMarketCap data, with a market capitalization of roughly $98.3 billion.
The broader cryptocurrency market told a different story. As capital rushed into Bitcoin ahead of the fork — driven by investors seeking the “free dividend” of Bitcoin Gold coins — alternative cryptocurrencies suffered significant declines. The Bletchley Ethereum Token Index had fallen 16% over the preceding month. Ethereum traded at $296.53, down from its recent highs. Ripple’s XRP sat at $0.2036, while Litecoin changed hands at $55.74, both showing weekly losses exceeding 6%.
Bitcoin Cash, the product of July’s hard fork, provided a cautionary tale. After hitting an all-time high of $914.45 following its creation, BCH had fallen steadily and was trading at approximately $338.20, with a market cap of $5.65 billion — a fraction of Bitcoin’s $98 billion valuation.
The Growing Debate Over Blockchain Forks
The Bitcoin Gold fork reignited an ongoing debate within the cryptocurrency community about the implications of creating new chains through hard forks. Critics argued that the practice undermined one of Bitcoin’s core value propositions — its limited supply.
“These forks are very bad for Bitcoin. Saturating the market with different versions of Bitcoin is confusing to users, and discredits the claim that there are a limited number of bitcoins — since you can always fork it and double the supply,” said Sol Lederer, blockchain director at Loomia, in a statement released on October 24.
Others took a more philosophical view. Bob Summerwill, chief blockchain developer at Sweetbridge, argued that forks are a natural and healthy part of any cryptocurrency ecosystem. “If a crypto-community has irreconcilable differences, then you can go your separate ways and that is just fine,” he said.
Mainstream Attention Grows as Big Tech Takes Notice
The fork drama coincided with growing mainstream interest in blockchain technology. On October 26, Microsoft published a video explainer about blockchain technology on its news portal, describing it as “the next frontier for digital transformation” and highlighting its applications beyond cryptocurrency in areas like banking, contracting, and voting.
The cryptocurrency market’s total capitalization stood at approximately $155 billion on October 26, with Bitcoin commanding roughly 63% market dominance. A CNBC survey conducted the previous week found that 49% of 23,118 respondents believed Bitcoin was headed above $10,000 — a prediction that would prove prescient within weeks as CME Group announced plans to launch Bitcoin futures on October 31.
Why This Matters
The Bitcoin Gold fork of October 2017 represents a pivotal moment in cryptocurrency history that established patterns still relevant today. It demonstrated both the technical feasibility and the market consequences of blockchain forks, while exposing the tension between decentralization ideals and the practical realities of governance. The event also highlighted Bitcoin’s extraordinary resilience — even as competing chains proliferated, Bitcoin’s dominance and price continued to strengthen, ultimately surging past $10,000 within weeks as institutional interest through CME futures legitimized the asset class in the eyes of traditional finance.
