One Bitcoin ‘Whale’ May Have Fueled the Currency’s Price Spike in 2017

A single Bitcoin holder — called a “whale” in cryptocurrency parlance — likely manipulated the market and helped fuel the big rise in Bitcoin’s price in 2017, according to researchers. That year, Bitcoin’s price jumped from under $1,000 in January to more than $19,000 in December. From a report: Last year, University of Texas professor John Griffin and Amin Shams, an instructor at Ohio State University, published controversial research concluding that in 2017 just a few big players used the stablecoin Tether to prop up the price of Bitcoin following market downturns. Griffin and Shams now tell Bloomberg that just a single whale was likely behind the behavior. They say that one entity on Bitfinex, a popular cryptocurrency headquartered in Hong Kong, appears able to push the price of Bitcoin up when it falls below certain thresholds. Griffin and Shams studied Bitcoin and Tether transactions from March 1, 2017, to March 31, 2018. They found that Bitcoin purchases on Bitfinex increased whenever the price dropped by certain increments. According to Bloomberg, which saw a prepublication version of a paper set to be published in the Journal of Finance, the authors conclude: “This pattern is only present in periods following the printing of Tether, driven by a single large account holder, and not observed by other exchanges.”
