In the firm's latest 10-Q quarterly report, filed to the U.S. Securities and Exchange Commission (SEC) on Tuesday, Aug. 14th, 2018, Riot Blockchain provided more details about the SEC's investigation into the firm's blockchain pivot, noting that the regulator is now looking into a number of the firm's registration statements, as well as its acquisition of a minority stake in Canadian crypto exchange Coinsquare. The filing stated: "The comments raise matters related to, among other things, the unsettled nature of accounting treatment for the Company's cryptocurrency mining and the fair value method selected by the Company (as opposed to intangible accounting methods proposed by some experts) and applicability to the Company of the Investment Company Act of 1940, particularly as relates to the Company's minority interest in goNumerical, Inc. a/k/a Coinsquare."
