Academic researchers at the University of Texas have concluded at least half of Bitcoin’s rise to a peak price of nearly $20,000 last year was due to manipulation by traders on Bitfinex, the primary Bitcoin exchange, using another cryptocurrency called Tether to boost prices when they dipped on other exchanges. The paper by John Griffin, a finance professor at the University of Texas, and graduate student Amin Shams, examined trading between March 2017 and March 2018 with particular focus on 87 periods each lasting one hour when Tether, which is issued exclusively by Bitfinex, flowed onto other exchanges when the price of Bitcoin was dropping.
“These 87 events account for less than 1 percent of our time series (over the period from the beginning of March 2017 to the end of March 2018), yet are associated with 50 percent of Bitcoin’s compounded return, and 64 percent of the returns on six other large cryptocurrencies (Dash, Ethereum Classic, Ethereum, Litecoin, Monero and Zcash),” the researchers wrote.

“There were obviously tremendous price increases last year, and this paper indicates that manipulation played a large part in those price increases,” Griffin told the New York Times, where the paper was first reported. Trading on Bitfinex, which is registered in the Caribbean with offices in Asia, is largely unregulated by any government.
Bitfinex CEO JL van der Velde denied any wrongdoing in a statement to Business Insider. “Bitfinex nor Tether is, or has ever, engaged in any sort of market or price manipulation.
Tether issuances cannot be used to prop up the price of Bitcoin or any other coin/token on Bitfinex,” van der Velde said. The researchers noted cryptocurrencies bear a striking similarity to well-researched investment bubbles stretching from the 18th century to the dot.com and housing crashes of recent years.
