In late 2017, Bitcoin captured global attention as its price skyrocketed to nearly $20,000—an unprecedented high that fueled both excitement and skepticism across financial markets. While many attributed the surge to growing public interest and speculative trading, a groundbreaking academic study now suggests a more controversial explanation: the rally may have been artificially driven by just one influential trader.
This revelation, based on in-depth transaction analysis, has reignited debates about market integrity in the cryptocurrency space and raised urgent questions about manipulation, transparency, and investor protection.
The Study Behind the Claim
A research paper co-authored by Professor John Griffin of the University of Texas and Assistant Professor Amin Shams of Ohio State University analyzed Bitcoin transaction data from March 2017 to March 2018. Their findings point to a single entity—referred to as a “large player” or “whale”—whose trading behavior significantly influenced Bitcoin’s price trajectory during this period.
The researchers argue that this trader executed large-volume purchases using Tether (USDT), a stablecoin pegged to the U.S. dollar, to buy Bitcoin on the Bitfinex exchange. These transactions were timed precisely during market downturns, consistently pushing prices upward shortly afterward.
"This one large player or entity either exhibited clairvoyant market timing or exerted an extremely large price impact on Bitcoin that is not observed in aggregate flows from other smaller traders," the authors stated in their paper, set for publication in the Journal of Finance.
While the study does not name the individual or group behind these trades, it highlights patterns consistent with market manipulation—specifically, the use of unbacked Tether tokens to inflate demand artificially.

Understanding Cryptocurrency Whales
In crypto markets, "whales" refer to individuals or entities holding vast amounts of digital assets. Due to the relatively low liquidity compared to traditional financial markets, a single whale can dramatically affect prices through large buy or sell orders.
Bitcoin whales often hold thousands of BTC, giving them outsized influence. For example:
- A sale of 5,000 BTC once triggered a flash crash, wiping $1,000 off Bitcoin’s value in under an hour.
- Conversely, coordinated buying sprees can create false signals of rising demand, luring retail investors into bullish positions.
These dynamics make cryptocurrencies particularly vulnerable to manipulation—especially when combined with opaque trading practices and limited regulatory oversight.
Market Volatility: Then and Now
Bitcoin's price has always been notoriously volatile. After peaking near $20,000 in December 2017, it plummeted throughout 2018, bottoming out below $4,000. This boom-and-bust cycle repeated multiple times, reflecting both speculative frenzy and structural weaknesses in market mechanics.
As of now, Bitcoin trades around $9,300, having briefly surpassed $12,000 earlier in the year. While still far from its all-time highs, the current upward trend has renewed optimism among long-term holders.
Several factors are contributing to renewed confidence:
- Growing institutional adoption
- Increased regulatory clarity in major economies
- Broader acceptance as a hedge against inflation
Yet volatility persists—driven not only by macroeconomic events but also by concentrated trading power within the ecosystem.
Could History Repeat Itself?
Despite increased scrutiny, concerns remain that similar manipulation could occur today. Although exchanges have improved transparency and reporting standards since 2017, many transactions still occur off public view or through private over-the-counter (OTC) desks.
Moreover, stablecoins like Tether continue to play a central role in crypto trading—especially on offshore platforms—raising ongoing questions about reserve backing and usage transparency.
Some experts believe that without stronger safeguards, the market remains exposed to coordinated influence campaigns that distort true price discovery.

Expert Predictions: Bullish Outlook Amid Skepticism
Despite past turbulence, many industry leaders remain bullish on Bitcoin’s long-term potential.
Changpeng Zhao (CZ), CEO of Binance—the world’s largest cryptocurrency exchange—recently predicted Bitcoin could reach $16,000 “soon-ish,” citing increasing adoption and network resilience.
Other prominent figures go even further:
- Tim Draper, venture capitalist and early Bitcoin advocate, believes it could grow more than 25-fold in value over the coming years.
- He estimates that at $250,000 per Bitcoin, the asset would represent just 5% of global currency markets—suggesting substantial room for growth.
- John McAfee, founder of the antivirus company bearing his name, famously claimed Bitcoin would hit $1 million by the end of 2020—a prediction now widely considered off-track.
While such forecasts attract headlines, they also highlight the speculative nature of crypto investing and the importance of critical analysis.
Frequently Asked Questions
Q: Who caused Bitcoin’s 2017 price surge according to the study?
A: Researchers suggest a single large trader—or "whale"—manipulated the market using Tether to buy Bitcoin during dips, artificially inflating its price.
Q: What is a Bitcoin whale?
A: A Bitcoin whale is an individual or entity holding a massive amount of BTC. Their trades can significantly impact market prices due to low liquidity.
Q: Is Bitcoin still vulnerable to manipulation today?
A: While exchanges have improved transparency, risks remain—especially with stablecoin usage and concentrated holdings. Regulatory oversight is still evolving.
Q: Did John McAfee’s $1 million Bitcoin prediction come true?
A: No. As of now, Bitcoin remains far below $1 million. McAfee’s forecast missed its 2020 target by a wide margin.
Q: Can one person still move the Bitcoin market?
A: It's less likely than in 2017 due to increased market size and institutional participation, but large players can still trigger short-term volatility.
Q: What role did Tether play in the alleged manipulation?
A: The study suggests unbacked Tether tokens were used to purchase Bitcoin on Bitfinex, creating artificial demand without real fiat backing.
The 2017 Bitcoin surge was more than just a speculative bubble—it may have been a carefully orchestrated event shaped by hidden hands. As the digital asset ecosystem matures, transparency, accountability, and regulation will be key to ensuring fairer markets.
Whether you're a seasoned trader or new to crypto, understanding these underlying forces helps build smarter investment strategies—and avoid being caught in the wake of manipulated waves.
