The U.S. Securities and Exchange Commission (SEC) has stopped the trading of a publicly-listed cryptocurrency firm’s stock.

In a notice, the SEC disclosed that it was freezing stock trading for The Crypto Company.

According to its website, the firm is based in Malibu, California, and provides consulting and investment services around cryptocurrencies.

The SEC said that it was making the move to pause trading because of issues over some of the information published by the company.

Plans outlined in public filings regarding the sale of shares by “insiders” also raised flags.

The trading freeze will last until January 3, according to the SEC.

The agency announced:

“The Commission temporarily suspended trading in the securities of The Crypto Company because of concerns regarding the accuracy and adequacy of information in the marketplace about, among other things, the compensation paid for promotion of the company, and statements in Commission filings about the plans of the company’s insiders to sell their shares of The Crypto Company’s common stock.

“Questions have also arisen concerning potentially manipulative transactions in the company’s stock in November 2017.”

“The Commission cautions broker-dealers, shareholders, and prospective purchasers that they should carefully consider the foregoing information along with all other currently available information and any information subsequently issued by the company.”

The little-known company has seen its stock surge recently.

The price is up more than 1,800% in the past month, with a market capitalization in excess of $11 billion.

The firm is one of a number of firms that have seen their stock prices spike amid a boom in the price of bitcoin and other cryptocurrencies.

The market surpassed $600 billion in total market capitalization the other day.

Crypto Company Recently Completed Stock Sale

As reported, The Crypto Company recently completed a stock sale for accredited investors at a price of just $7.

Investors usually expect a discount in exchange for participating in these sales.

However, a markdown of this size is rare and wholly unprecedented.

“It looks funny when you’re sitting here like this,” remarked Michael Poutre, chief executive of the firm.

Crypto Currency invests and trades digital assets, and develops source code for managing them, according to its regulatory filings.

The $7 offering price was communicated to potential buyers weeks ago before the stock surged more than 3,000 percent to its $642 peak on December 11.

Crypto is the product of a reverse merger with a company that made water and radio-wave resistant sports bra pockets, according to a November filing.
