Bitcoin plunged to a new 2018 low of $5,787 on June 24, dragging the entire altcoin market into a relentless selloff that wiped nearly $19 billion from total cryptocurrency valuations in just three days. The crash pushed the total market capitalization below $241 billion, a far cry from the $830 billion peak reached just six months earlier.
TL;DR
- Bitcoin hit $5,787 on June 24, its lowest price of 2018, representing a 70%+ decline from December 2017 highs
- Total crypto market cap fell from approximately $260 billion to $241 billion over the weekend
- EOS led losses among top-10 altcoins, plunging 22.42% over seven days
- Ethereum dropped to $457.67, losing 8.43% in 24 hours
- Japan imposed new exchange restrictions on June 22, adding to bearish pressure
Blood in the Water: Altcoins Take a Beating
The weekend of June 23-24, 2018, marked one of the most punishing stretches in what was already a brutal bear market. As Bitcoin carved out fresh lows for the year, altcoins bled even harder. EOS, which had climbed into the top five cryptocurrencies by market capitalization with a valuation of $7.25 billion, suffered a staggering 22.42% weekly decline — the worst performer among the top ten coins by a significant margin.
Ethereum, the second-largest cryptocurrency, wasn’t spared either. ETH traded at $457.67 on June 24, down 8.43% in the previous 24 hours alone and 8.43% over the week. With a circulating supply of over 100 million ETH, the network’s market cap stood at roughly $45.9 billion — a fraction of what it had been at the height of ICO mania just months earlier.
Ripple’s XRP held the third spot at $0.4774, shedding 9.54% over the week. Bitcoin Cash at $749.37 dropped 11.64%, while Litecoin tumbled 15.95% to $80.78. The uniformity of the decline was striking: regardless of individual project milestones, technical achievements, or business partnerships, virtually every major token moved in lockstep with Bitcoin.
EOS: The Hardest Hit Among the Giants
EOS bore the brunt of the altcoin carnage. After its record-breaking $4 billion ICO concluded earlier in June, the token faced intense selling pressure. Trading at $8.09 on June 24 with a market cap of $7.25 billion, EOS had lost nearly a quarter of its value in just one week. The selloff came despite the much-hyped mainnet launch, which had been plagued by technical difficulties and delays in block producer voting.
The contrast between EOS’s massive fundraising success and its price performance highlighted a growing disconnect between project valuations and market sentiment. For a third consecutive day, EOS recorded some of the largest percentage declines among major cryptocurrencies.
Regulatory Headwinds from Japan
Adding fuel to the fire, Japan’s Financial Services Agency (FSA) imposed new restrictions on cryptocurrency exchanges on June 22. The regulatory crackdown came in the wake of the Coincheck hack earlier in the year, which saw the theft of approximately $530 million worth of NEM tokens. Japanese authorities ordered several exchanges to improve their security measures and compliance protocols, potentially constraining investment flows from one of the world’s most active crypto markets.
The Japanese action was part of a broader global regulatory tightening that had been weighing on crypto markets throughout 2018. From the SEC’s aggressive pursuit of fraudulent ICOs to China’s ongoing hostility toward digital asset trading, regulators worldwide were sending a clear message that the wild west era of cryptocurrency was ending.
Tether Manipulation Allegations Linger
The crash also occurred against the backdrop of a damning academic study released earlier in June by University of Texas finance professor John Griffin and co-author Amin Shams. The research argued that at least half of Bitcoin’s meteoric rise in 2017 was fueled by coordinated price manipulation using Tether (USDT), the dollar-pegged stablecoin issued by Bitfinex.
According to the study, large purchases of Bitcoin were systematically made at moments of price weakness using newly minted Tether tokens, effectively propping up the market during downturns. The allegations cast a long shadow over the entire crypto market, contributing to battered investor sentiment and raising fundamental questions about the legitimacy of the previous year’s rally.
Why This Matters
The June 24 crash wasn’t just another down day in a bear market — it represented the convergence of multiple systemic risks that were reshaping the crypto landscape. Regulatory crackdowns in Japan and elsewhere, mounting evidence of market manipulation, the collapse of the ICO bubble, and internal Bitcoin community conflicts all contributed to a crisis of confidence that would take months to resolve.
For altcoins, the event underscored a painful reality: in the absence of mature, independent markets, even the most technically innovative projects remained tethered to Bitcoin’s gravitational pull. EOS’s 22% weekly decline despite its record-breaking token sale demonstrated that hype alone couldn’t sustain valuations when macro sentiment turned negative.
