SINGLE WHALE BEHIND BITCOIN’S DEC 2017 RALLY

John Griffin, a professor at the University of Texas, and Amin Shams, an assistant professor at Ohio State University, jointly updated an article they first published in 2018, indicating that a single entity on  bitfinex had changed bitcoin prices in 2017.

The updated, peer-reviewed document, shared with Bloomberg and published in a forthcoming Journal of Finance, examined stable transactions in USD and Bitcoin between March 1, 2017 and March 31. 2018, concluding that the purchases of the BTC. Bitfinex has increased every time the bitcoin value has decreased for some increments.

"Our results suggest that instead of thousands of investors moving the price of bitcoin, it's a big price," Griffin told Bloomberg, adding: "Now, people will be surprised that investors are delivering billion to people who did not know, and who faced little supervision. "

Bitfinex's general advisor, Stuart Hoegner, rejected these claims, saying the document was "fundamentally flawed" because it is based on an insufficient data set. "This is clearly an attempt to use the academy's appearance to get a mercenary reward, whether it updates it or not, the document has no academic rigor," he said. Hoegner.

Last month, Bitfinex and Tether issued separate statements, stating that they knew that "an unpublished, unpublished document falsely elevated Tether's figures to be responsible for manipulating the Criptomoneda market." However, the updated document is remarkably revised as well. .

In his first work, Griffin and Shams said the link "was used to stabilize and manipulate" bitcoin prices in 2017. At the same time, Bitfinex rejected the applications, and its managing director, JL van der Velde "Bitfinex , nor is Tether, or has participated in any type of market or price manipulation. "
