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.
The news: 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.
