Note 6. Investment in Coinsquare:

In September 2017, the Company acquired a minority interest for $3.0 million in Coinsquare, which operates a digital crypto currency exchange platform in Canada. During February 2018, the Company invested an additional $6.4 million to acquire additional common stock of Coinsquare. The investment included an additional equity investment of $2.8 million that was part of an approximate $24 million financing by Coinsquare. Additionally, warrants acquired in the original investment were exercised in exchange of a cash payment of $3.6 million. These additional investments resulted in a current ownership in Coinsquare by the Company of approximately 12% based upon Coinsquare’s issued and outstanding shares. The Company has evaluated the guidance in ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, and elected to account for the investment using the measurement alternative as the equity securities are without a readily determinable fair value and do not give the Company significant influence over Coinsquare. The measurement alternative at cost, less any impairment, plus or minus changes resulting from observable price changes. As of March 31, 2019 and December 31, 2018, the Company considered the cost of the investment to not exceed the fair value of the investment and did not observe price changes.
