BlackRock did not immediately respond to a Reuters request for comment on the matter.
The decision comes at a time when the global cryptocurrency industry is in the crosshairs of the United States securities regulator for alleged violations of stock trading laws.
In early June, the United States Securities and Exchange Commission (SEC) sued Coinbase, the largest American crypto-asset exchange platform, accusing it of operating illegally without having previously registered with the regulator.
The lawsuit was filed in federal court in Manhattan, a day after the SEC sued Binance, the world’s largest cryptocurrency exchange, and its founder Changpeng Zhao, for alleged violations of securities law.
The high-profile measures taken by the regulator are having repercussions in the digital asset industry.
