Professor at the University of Texas: A giant whale boosted the price of bitcoin in 2017

University of Texas professor John Griffin and Ohio State University's Amin Shams updated their first paper published in 2018. In last year's paper, they claimed that the soaring bitcoin in 2017 may be triggered by manipulation. Now, they have come up with a new claim that a whale may be the driving force behind misconduct, and it seems to have the ability to change prices at will.
John Griffin said in an interview: "Our findings show that the price of Bitcoin is not driven by thousands of investors, but by a large investor."
