The U.S. Securities and Exchange Commission (SEC) is asking a court to allow "alternative means" of serving documents on cryptocurrency exchange Binance and its CEO Changpeng Zhao, as the executive is "known for protecting his whereabouts." The SEC on Monday sued Binance and Zhao for violating securities laws and asked the District Court for the District of Columbia to allow it to serve any legal documents during the investigation leading to the legal case by sending copies of the documents to attorneys representing the parties. The move hits the heart of the struggling crypto industry, with the SEC's regulatory web now covering $120 billion in cryptocurrencies following the actions by Coinbase and Binance.
