A bitcoin and litecoins exchange has stopped trading due to a new trading ban, after reports that a number of companies had failed to register as bitcoin exchanges, and that some traders had bought or sold them to buy and sell the altcoins.
Trading on the platform, known as Nasdaq, resumed on Monday.
The New York-based exchange has been the subject of a number in recent days of accusations of fraud and theft, including an allegation that a trader was paid $5,000 to buy a number, and then later sold it for $2,000.
The company has since taken down its trading ban and has also refunded customers who bought or traded for the altcoin before the suspension.
A spokesman for Nasdaq told CoinDesk that it had suspended trading on its platform as a precaution after a “minor issue”.
“As part of our ongoing investigation, Nasdaq has suspended trading as a safety measure,” the spokesman said.
The move came after the company announced on Monday that it would halt trading for two weeks.
According to a statement from Nasdaq on its website, the ban applies to trading on Nasdaq.com, the platform’s trading platform.
The statement added that the ban will not affect trading on other trading platforms, including those listed on NasDAQ.com.
However, Nasixx.com and Nasdaq’s website have not responded to CoinDesk’s requests for comment.
“Nasdaq has implemented a temporary suspension of trading on our platform as precautionary measures,” the statement read.
“We are reviewing the suspension and will provide updates in the coming days.”
In a statement to CoinStreet, Nasaxx.org said that the suspension was a temporary measure and that Nasdaq would continue to work with customers to provide a more secure and secure platform.
In a follow-up statement, the company said it was “reviewing the matter”.
“We take these matters very seriously and are taking steps to address them,” it said.
It added that “all of our customers and employees are expected to adhere to the new rules and protocols, and we will continue to update customers and our employees on the status of this.”
CoinDesk contacted NasaxX.org, NasDAQ and NasaxEx.com but neither were available for comment at the time of publication.
On the other hand, a Twitter account called @NasaxX posted a statement on Monday saying that it “will no longer be trading on NASDAQ” and that it was shutting down.
It said it had purchased and sold the platform before the ban was imposed.
“The Nasdaq Trading platform has been closed for a brief period as a temporary precautionary measure,” it added.
“This temporary suspension does not affect all trading activity.”
Nasdaq did not immediately respond to CoinMarketCap’s request for comment on the ban.
Bitcoin exchanges have been a hot topic for many investors in recent weeks.
The price of bitcoin, as it is known, has been surging since the start of the year, with the market capitalisation of bitcoin currently hovering above $20bn.
Many investors have bought and sold bitcoin to hedge their positions against volatility, and also for use as a currency to exchange between countries, such as the UK.
