Something is not right.
Humans are notoriously bad[1] at generating random numbers. We're amazingly predictable. That's why the distribution of trade volumes on Kraken's USD/USDT pair looks awfully suspect.
"I've looked through lots and lots of data, and I don't think this is real," said Rosa Abrantes-Metz[2], a professor at New York University's Stern School of Business and an expert on manipulation.
Kraken's bitcoin trade reflects fairly typical human behavior (with volumes clustered around 0.01, 0.1, and 1 BTC). By comparison, its USDT order book looks downright bizarre.

More importantly, based on price and volume data, the exchange's USD/USDT order book seems to violate basic tenets of economics. Large and small trades have virtually the same impact on prices (that is, almost no impact). When you think about the dynamic relationship between supply and demand, this doesn't make any sense.

"The mystery is bracketed by another quirk: Oddly specific order sizes – many going out to five decimal points, with some repeating frequently. Another red flag," Bloomberg wrote.
Tether has become the open secret of the cryptocurrency world. It's the elephant in the room – the inconvenient truth. While bitcoin believers and Ether enthusiasts worship their pretty trading charts, Tether is the nasty undercurrent
