The Hook
On August 19, 2017, the cryptocurrency market witnessed a dramatic divergence that left traders scrambling to reposition. While Bitcoin retreated 7% overnight from its weekly highs near $4,483, Bitcoin Cash—the chain born just nine days earlier—exploded upward in a relentless three-day rally that pushed its price past $900 and its market capitalization beyond $18 billion. The contrast between the two Bitcoin chains told a story of a community fractured by disagreement, with capital flowing decisively toward the upstart fork.
On-Chain Evidence
The data from Kraken’s daily market report painted a vivid picture of the shifting landscape. BCH closed the day at $784.52, up 17.9%, with an astonishing $104 million in volume on that single exchange alone. Bitcoin, by comparison, dipped 0.63% to $4,104 on $67.7 million in Kraken volume. But the real story was in the global aggregates: BCH trading volume across all exchanges reached $3.6 billion on August 19, eclipsing Bitcoin’s $2.9 billion for the first time since the fork. The younger chain was commanding more trading activity than the king itself.
According to Coin Dance statistics, Bitcoin Cash mining was 66% more profitable than Bitcoin mining at current prices. Miners had already found 1,109 blocks on the BCH chain at approximately 13% of Bitcoin’s difficulty. Perhaps most notably, an 8MB block was mined on the BCH network earlier in the week, clearing over 37,000 transactions in a single block—a stark demonstration of the larger block size philosophy that had driven the fork.
The Core Conflict
The rally’s catalyst lay in the escalating tensions between Bitcoin Core developers and supporters of the SegWit2x compromise. The New York Agreement, brokered in May 2017, had promised a two-step upgrade: first the activation of Segregated Witness (SegWit), then a hard fork to increase the base block size to 2MB. SegWit locked in on August 9 and was scheduled for full activation on August 24. But as the activation date approached, Core developers made it increasingly clear they would not support the second half of the agreement—the 2MB hard fork.
This public fracturing between BitPay, the Core development team, and other key industry players sent a wave of uncertainty through the market. Traders who had backed the SegWit2x compromise suddenly found themselves looking for alternatives. Many began treating Bitcoin Cash as a sort of “lifeboat”—a chain that had already implemented larger blocks through its hard fork on August 1. If the New York Agreement collapsed entirely, BCH would remain standing with its 8MB blocks already operational.
Market Implications
The South Korean market emerged as the epicenter of the BCH trading frenzy. Exchanges like Bithumb, Coinone, and Korbit processed over $1.5 billion in BCH-KRW trading pairs. South Korean premiums pushed local BCH prices above $1,100, reflecting the intense retail demand that characterized the Korean crypto market throughout 2017. Beyond Korea, major volume came from Bitfinex, Poloniex, Kraken, and Bittrex, indicating broad global participation rather than a regional phenomenon.
For holders who had maintained their 1:1 BCH allocation since the fork, the combined value of BTC plus BCH holdings remained remarkably stable at roughly $4,600-$4,800—suggesting the market was treating the two chains as components of a single original value proposition rather than entirely independent assets. The Relative Strength Index (RSI) for BCH was heading south, indicating overbought conditions that could lead to near-term price consolidation. However, the short-term Simple Moving Average remained well above the long-term SMA, suggesting bullish momentum had not yet been exhausted.
Ethereum held steady at $295.50, up 1.09%, showing that the broader altcoin market was not yet participating in the rotation toward BCH. Dash surged 31.2% to $293.70, and Monero gained 15.3% to $55.20, suggesting parallel momentum in privacy-focused and alternative payment coins. Litecoin edged up 1.28% to $45.04, while XRP declined 4.32% to $0.1557. Total Kraken volume across all markets reached $226 million for the day.
The Verdict
August 19, 2017, marked a pivotal moment in Bitcoin’s governance crisis. The Bitcoin Cash rally was not merely a speculative event—it was a market referendum on the block size debate that had consumed the community for years. With SegWit activation just days away and the 2MB hard fork commitment crumbling, capital was making its preferences known. Whether BCH would sustain its momentum depended entirely on whether the SegWit2x agreement would hold together or collapse entirely. As the dust settled on this chaotic Saturday, one thing was clear: Bitcoin’s identity crisis was far from over, and the market was pricing in multiple possible futures.

BCH doing $3.6B volume and beating BTCs $2.9B on Kraken. Say what you want about the fork but the market was speaking loudly
the capital rotation from BTC to BCH that week was something else. BTC bleeding 7% while its own fork pumped 100%+ in 3 days
that 17.9% daily gain with $104M on a single exchange was absolutely nuts for a 9-day-old chain
