Zaif, a Japanese cryptocurrency trade exchange, has recently faced a million dollar attack and has suspended all trading operations of Bitcoin, MonaCoin, and Bitcoin Cash as a result.
The document states that:
“The Commission is instituting proceedings to allow for additional analysis of the proposed rule change’s consistency with Section 6(b)(5) of the Act, which requires, among other things, that the rules of a national securities exchange be ‘designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade,’ and ‘to protect investors and the public interest’.”
