This is the second phase of TradeStation's crypto expansion plan, which began when the subsidiary became one of the first online brokers to offer real-time market data for CME and CBOE bitcoin indices in early 2018. Along with TradeStation, holding company Monex made another big investment in the crypto space last year — taking major Japanese exchange Coincheck under its wing after it was hacked, providing the exchange with funding, and turning it into a subsidiary company. Prior to this, Coincheck had been in the process of registering as a "quasi-operator" in accordance with the amended Payment Services Act of April 2017, which introduced a registration system for unregulated Japanese cryptocurrency exchange providers. This process was delayed by the hack, in which around $500 million was stolen. As a Monex Group's subsidiary, Coincheck underwent a security and compliance overhaul and completed the process of becoming a registered cryptocurrency exchange operator in Japan earlier this month.
