The world’s largest cryptocurrency exchange, Binance, added to the widespread industry concerns surrounding Tether (USDT) when they suspended withdraws of the stable coin on Monday morning during what they claimed was a period of heightened trading activity.

Binance’s move to suspend USDT trading came amidst unprecedented trading activity on the controversial and widely utilized stable coin, in which the token, which is intended to match the value of the US Dollar, dipped to a low of $0.92, before rising to its current price of $0.98.

Many analysts attributed the major rise in Bitcoin’s price to the Tether dump, which may have been caused by investors, or a single investor, selling massive amounts of the stable coin for Bitcoin in fear of it imploding in the near future due to unsubstantiated insolvency concerns circulating in the cryptocurrency community.

Following the unusual USDT trading activity, Binance moved to suspend USDT trading and withdraws, informing site users with the generic message: “wallet maintenance, withdrawal suspended.”

During this time, a rumor surrounding the situation surfaced, with an image apparently showing a message explaining that the exchange was planning on delisting the stable coin due to the concerns surrounding it, but this rumor was largely discredited after USDT trading went back online.

Unfortunately, trading was only live for 15 minutes before the exchange once again suspended trading, citing the same issues with wallet maintenance, and online customer service representatives telling customers that trading was suspended due to network congestion.

Binance CEO, Changpeng Zhao, tweeted about the rumors regarding the delisting of USDT, saying that it was “a single photoshopped fake announcement.” Despite this, Zhao has been quiet on the rumors since then, not responding to multiple requests for comments from major media outlets.

Binance is the world’s largest holder of USDT tokens, holding more than 768.5 million in its reserve according to Tether.to. This being said, it is highly unlikely that the exchange would jeopardize the value of a stockpile this significant simply due to some uncorroborated concerns surrounding the stable coin.
