TL;DR
- China’s PBOC banned ICOs on September 4, sending shockwaves through the token sale ecosystem
- Ethereum lost nearly 16% in a week, dropping to $312.99 as ICO-funded projects faced existential uncertainty
- OmiseGO (OMG) bucked the trend with a 25.46% daily gain, suggesting selective investor confidence

- Bitcoin showed relative resilience at $4,376, recovering 3.28% on the day
The cryptocurrency market woke up to a new reality on September 5, 2017. One day after China’s People’s Bank of China (PBOC), along with six other government agencies, declared Initial Coin Offerings (ICOs) to be a form of illegal fundraising, the entire token economy was reeling from the implications.
For months, ICOs had been the lifeblood of the nascent decentralized finance ecosystem. Projects built on Ethereum’s smart contract platform had raised billions of dollars through token sales, creating a vibrant — if sometimes reckless — marketplace for blockchain innovation. China’s blanket ban threatened to pull the rug out from under this entire model.
Ethereum Bears the Brunt as ICO Pipeline Freezes
Ethereum, the platform of choice for the vast majority of ICOs, suffered the most severe damage. According to CoinMarketCap data, ETH was trading at $312.99 on September 5, representing a staggering 15.86% decline over the previous seven days. The token that had powered everything from prediction markets to decentralized exchanges was now the poster child for regulatory vulnerability.
The logic was brutal in its simplicity. If China — home to some of the world’s most active crypto traders and a significant portion of ICO activity — was banning token sales, who would be next? South Korea? The United States? The European Union? Each hypothetical ban represented a potential death blow to projects that had built their entire funding model around token distribution.
The fear was particularly acute for projects in the DeFi pipeline. Dozens of decentralized applications were in various stages of token sale planning. Many had based their financial projections on Chinese participation. Overnight, those projections became worthless.
OmiseGO Defies the Selloff
In a remarkable counter-narrative, OmiseGO (OMG) surged 25.46% on September 5, trading at $10.98. The Thailand-based decentralized exchange project, backed by Ethereum co-founder Vitalik Buterin, appeared to benefit from a flight to quality within the altcoin space.
Investors seemed to be making a clear distinction between speculative ICO tokens with no working product and established projects with real technological foundations. OMG’s decentralized exchange architecture, designed to enable trustless cross-chain transactions, represented exactly the kind of infrastructure that could make token economies more resilient — ironically, exactly what the market needed in the face of regulatory pressure.
The OMG rally suggested that while the ICO gold rush might be ending, the underlying technology was far from dead. Smart money was rotating from speculative token sales into platforms building actual financial infrastructure.
Bitcoin’s Relative Stability Signals Maturation
While Ethereum and ICO-dependent tokens were in freefall, Bitcoin demonstrated remarkable resilience. At $4,376.53, BTC was actually up 3.28% on the day, though it remained 4.65% lower on the week. This divergence told an important story.
Bitcoin’s status as the original cryptocurrency — and one with no ICO history — insulated it from the worst of the regulatory panic. While China’s ICO ban targeted token sales specifically, Bitcoin was widely understood as a commodity rather than a security. This distinction, while still debated by regulators worldwide, provided a psychological floor for the flagship cryptocurrency.
The total Bitcoin market capitalization stood at $72.4 billion on September 5, with 24-hour trading volume of nearly $2.7 billion. These were not the numbers of a market in terminal decline. They were the numbers of a market going through a painful but potentially necessary correction.
The Decentralized Finance Dilemma
China’s ICO ban forced the young DeFi community to confront an uncomfortable reality. Building decentralized financial systems on top of centralized fundraising mechanisms created an obvious point of failure. Projects that had planned to launch through Chinese-facing token sales now had to completely rethink their go-to-market strategies.
Some projects immediately began exploring alternative models: airdrops, decentralized token distributions, and direct integration with existing DeFi protocols. The crisis, while painful in the short term, would ultimately push the ecosystem toward genuinely decentralized funding mechanisms.
The market data told the story of this transition. NEO, often called “China’s Ethereum,” was among the hardest hit, down 32.31% on the week at $22.80. Projects with the strongest Chinese exposure suffered the most. Meanwhile, Bitcoin Cash held relatively steady at $541.71, down just 1.26% on the week, suggesting that the market was differentiating between tokens based on their regulatory risk profiles.
Why This Matters
The China ICO ban of September 2017 was a watershed moment for decentralized finance. It exposed the fundamental tension between decentralized technology and centralized regulatory power, forcing the crypto industry to mature rapidly. Projects that survived the crackdown emerged stronger, more decentralized, and better equipped to navigate the regulatory landscape. The events of September 5 — with Ethereum’s sharp decline contrasting against Bitcoin’s stability and OMG’s surprising rally — revealed which projects had genuine foundations and which were built on sand. This pattern of regulatory shock followed by market maturation would repeat itself many times in the years to come, but the China ICO ban remains the template.

OMG surging 25% while everything else bled was wild. that project had so much hype in 2017
OMG hit $12 a few weeks after this. the hype was insane but at least they had actual payment infrastructure in southeast asia
25% on pure speculation with zero working product. 2017 in a nutshell
OMG had vitalik on the advisory board and a real plasma pitch. pure speculation is harsh, it had more narrative backing than 99% of 2017 tokens
defi_dad vitalik advising meant nothing for OMG long term. token went from $25 to $0.30. the plasma pitch was abandoned by OMG themselves
onchain_dive_ plasma was supposed to be the scaling fix and OMG abandoned it within a year. vitalik quietly moved on to rollups and left OMG holders bagholding
onchain_dive_ ICO to DeFi to NFTs every ETH use case gets hyped then abandoned. plasma was supposed to be the scaling solution lmao
omg_bag_ OMG surging 25 pct while everything burned was peak 2017 hopium. that token had vitalik advisory and plasma dreams. ended at 30 cents
ETH dropping 16% to $312 while BTC only dipped 3% tells you how exposed ethereum was to the ICO model
ETH was basically the ICO settlement layer back then. no DeFi, no staking, just token sales. the ban hit it way harder
exactly. ETH was the settlement layer for like 90% of ICOs at that point. the PBOC ban basically pulled the plug on the entire use case overnight
Chen Wei 90% of ICOs were on ETH and the PBOC knew exactly what they were doing. target the settlement layer and the entire ecosystem freezes
BTC recovering 3.28% while ETH bled 16% says everything about how overexposed ethereum was to the ICO casino. the flippening narrative took a massive hit here
ETH bleeding 16% to $312 while BTC held $4,376. thats when everyone learned ETH was basically a leveraged bet on token issuance
BTC at 4376 recovering 3.28 pct while ETH bled 16 pct. bitcoin was the safe haven even back then. the pattern never changes
