Latest article by www.wired.co.uk stated that a newspaper by researchers  at the University of Texas at Austin's department of finance indicates that someone at Bitfinex cryptocurrency exchange may have artificially inflated the price of coins including bitcoin, ether, and Zcash. The responsible for this appears to have been Tether, a cryptocurrency with the same CEO as Bitfinex.
What are your thoughts about this? Do you think they really manipulated the price? Is it possible?
