According to the agency, Poloniex also allowed trading in unregistered digital assets from 2017 through 2019.Poloniex was therefore classified as a securities exchange. The SEC also stated in a legal order that Poloniex had failed to register. Poloniex didn't admit to wrongdoing, but he agreed to the settlement.Kristina Littman (chief of the SEC’s cyber enforcement division), stated that "Poloniex chose to increase profits over compliance with federal securities laws by including electronic asset securities on its unregistered Exchange."Hester Peirce (Commissioner), has frequently criticized SEC rulings. She claimed that Poloniex was held to an inapplicable standard by the agency.Peirce wrote in sharply crafted dissent, "Yes, Poloniex could've tried to register as either a securities exchange, or more likely as a broker-dealer."
