> One entity on the cryptocurrency exchange Bitfinex appears capable of sending the price of Bitcoin higher when it falls below certain thresholds, according to University of Texas Professor John Griffin and Ohio State University’s Amin Shams. Griffin and Shams, who have updated a paper they first published in 2018, say the transactions rely on Tether, a widely used digital token that is meant to hold its value at $1.
> “Our results suggest instead of thousands of investors moving the price of Bitcoin, it’s just one large one,” Griffin said in an interview. “Years from now, people will be surprised to learn investors handed over billions to people they didn’t know and who faced little oversight.”
> “This pattern is only present in periods following printing of Tether, driven by a single large account holder, and not observed by other exchanges,” they wrote in their new peer-reviewed paper, set to be published in a forthcoming Journal of Finance.
> “Simulations show that these patterns are highly unlikely to be due to chance. 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.”
