On August 14, 2018, Ethereum was in freefall. The second-largest cryptocurrency by market capitalization had already lost 39% of its value in the first two weeks of August alone, and the selling pressure showed no signs of abating. Ether dropped another 13% during the day’s trading sessions, briefly touching $261.80 on Kraken — a level that would have been unthinkable during the mania of late 2017, when one ETH traded above $1,400.
TL;DR
- Ethereum plunged 39% in the first two weeks of August 2018, with another 13% drop on August 14 alone
- Ether’s share of total crypto market cap collapsed from a peak of 32% to just 14%
- ICO projects liquidating ETH holdings identified as a primary driver of the selloff
- Bitcoin dominance surged to 54% as investors fled altcoins for the relative safety of BTC
- Total crypto market cap fell below $200 billion, down from $835 billion at January’s peak
The ICO Hangover Reaches a Breaking Point
The roots of Ethereum’s dramatic decline traced back to the ICO boom of 2017, when hundreds of blockchain projects raised billions of dollars worth of Ether through token sales. At the height of the fundraising frenzy, these projects accumulated vast ETH treasuries that were now rapidly losing value. As prices declined throughout 2018, an increasing number of ICO-funded projects began liquidating their Ethereum holdings to cover operational costs — creating a self-reinforcing cycle of selling pressure.
Timothy Tam, CEO of cryptocurrency intelligence platform CoinFi, put it plainly: “ICOs that have raised a lot of money are really feeling a lot of pain as their crypto holdings lose value.” The scale of the unwinding was staggering. Ethereum had dominated the ICO landscape as the primary platform for token launches, and now the very projects built atop it were contributing to its decline.
The numbers told the story of a dramatic reversal. At the height of Ethereum’s rally, the cryptocurrency commanded 32% of the total digital asset market capitalization — coming within striking distance of Bitcoin’s 39%. By August 14, Ether’s dominance had collapsed to just 14%, while Bitcoin’s share had surged to 54% as investors sought refuge in the market’s most liquid and established asset.
Blood in the Altcoin Streets
The carnage extended well beyond Ethereum. Virtually every major altcoin suffered significant losses on August 14, with all but three of the top 100 cryptocurrencies by market capitalization posting declines over the past 24 hours. The total market capitalization of all digital assets hovered around $195 billion to $199 billion — a breathtaking collapse from the $835 billion peak reached just seven months earlier in January.
Cardano (ADA) was the biggest loser among the top ten, plummeting 16.8% and dropping to the eighth position by market cap. EOS declined 13.7% to $4.33, while Bitcoin Cash (BCH) fell 15% and touched an intraday low of $472 on Bitstamp. Ethereum Classic (ETC) shed 12.8% to trade at $10.88, and Monero (XMR) dropped 10.6% to $80.98.
Kraken’s daily market report painted a bleak picture: $222 million traded across all markets on the exchange, with virtually every asset in the red. Bitcoin itself was not immune, falling 3.08% to $6,091, but its losses were modest compared to the devastation in the altcoin space.
Bitcoin: The Relative Winner in a Losing Market
In a day when nearly everything was falling, Bitcoin emerged as the relative outperformer. While BTC dropped 3.94% on the day — briefly touching $5,880 during overnight trading — its losses were a fraction of those suffered by Ethereum and other altcoins. The result was a significant spike in Bitcoin dominance, which climbed above 54% for the first time in months.
This dynamic reflected a broader flight to quality within the cryptocurrency ecosystem. Investors who remained in the market were consolidating their positions into Bitcoin, viewing it as the most resilient digital asset during a period of extreme uncertainty. The top five exchanges handling the most BTC volume were Bitflyer, OKEx, Bitfinex, Binance, and Coinbene, with Tether (USDT) accounting for 50.2% of all Bitcoin trading volume.
Samson Mow, chief strategy officer at Blockstream, offered a blunt assessment of the market conditions. “Most cryptocurrencies have been overvalued for a very long time,” Mow said. “It’s hard to pin this move on any particular factor, but it feels like the opposite of last year when money piled in as people felt FOMO. Now it’s piling out as they sense panic.”
Global Factors Largely Irrelevant
The selloff occurred against a backdrop of significant global market turbulence, most notably Turkey’s escalating currency crisis. The Turkish lira had lost approximately 25% of its value, raising questions about whether broader emerging market stress was spilling over into cryptocurrency markets. James Quinn, head of markets at Kenetic, dismissed the connection, noting that correlations between cryptocurrencies and traditional asset classes have historically been extremely low. “Which is one of the reasons why there is interest in this space and why people want to make an allocation in this space,” he added.
However, anyone hoping Bitcoin would serve as a hedge against global market chaos was disappointed. The cryptocurrency’s decline against the dollar in August was nearly as severe as the Turkish lira’s plunge, undermining the narrative that digital assets could function as a safe haven during periods of traditional market stress.
Why This Matters
The events of August 14, 2018, exposed the structural fragility of the ICO-driven ecosystem that had fueled much of the 2017 cryptocurrency boom. Ethereum’s collapse was not merely a price decline — it was the unwinding of an entire economic model built on token sales and ETH-denominated treasuries. The shift in market dominance from ETH to BTC reflected a maturation of investor sentiment, as market participants increasingly differentiated between established cryptocurrencies and the flood of speculative tokens that had proliferated during the bull run. The day also demonstrated that Bitcoin, despite its relative resilience, was not yet the safe-haven asset that some advocates envisioned. For the broader market, the $643 billion evaporation from the January peak served as a sobering reminder of the speculative excess that had defined the previous year.
