Last year, two academics concluded that the Bitcoin price rally in 2017, when BTC hit the all-time high, was caused by manipulation. Now the research authors figured out that the surge was likely caused by a single entity. University of Texas Professor John Griffin and Ohio State University’s Amin Shams shared their updated research paper with Bloomberg where they double down on past claims that Tether, the biggest stablecoin issuer, was the sole reason the Bitcoin price surged to its insurmountable all-time high of $20,000 at the end of 2017. Now, the academics claim that a single Bitfinex whale was actually responsible for fueling Bitcoin's rocket to the moon.
