Trading of two cryptocurrencies have been temporarily suspended because they are not identified correctly and could mislead consumers, federal regulators said.

The U.S. Securities and Exchange Commission suspended the trading of Bitcoin Tracker One and Ether Tracker One until to give exchange XBT Provider time to clear up confusion about the nature of both cryptocurrencies.

“It appears … that there is a lack of current, consistent and accurate information,” the SEC said in a filing Sunday. “The commission is of the opinion that the public interest and the protection of investors require a suspension of trading in the securities.”

Both cryptocurrencies are listed on XBT Provider websites and applications as exchange-traded funds that track a basket of assets. In reality, they’re non-equity linked certificates. XBT Provider is owned by London-based investment firm CoinShares.

The SEC has been under pressure from investors to allow exchange-traded funds on the stock market but has so far rejected every proposal.

The SEC decision could increase the already volatile cryptocurrency market, with Bitcoin trading up 1.6 percent in Monday trading.
