Ripple CEO Brad Garlinghouse told Fortune Magazine today that he expects the SEC to sue the company imminently for selling unlicensed securities. XRP, Ripple’s cryptocurrency, is valued at $23 billion, the third largest cryptocurrency by market cap

Garlinghouse said that he believes the SEC will name him and co-founder Chris Larsen as co-defendants in a lawsuit, which he expects to be brought in the near future.

The price of XRP had dropped more than 13% by late Monday, below 50 cents.

Garlinghouse told the Wall Street Journal that a representative of the Commission told Ripple late Monday that it would be filing its lawsuit in federal district court soon. The CEO told the newspaper it intended to fight back: “They’re wrong in matter of law and fact,” he told the Journal.

Ripple issued XRP in 2012. The SEC, apparently, believes that XRP, unlike Bitcoin or Ethereum, is a security and should have been registered with the Commission as such. Ripple holds some 6.4 billion XRP. It periodically sells the cryptocurrency to the public from an escrow account that holds another 48 billion.

The right side of history

The issue of whether XRP is a currency or a security has been argued for years among crypto enthusiasts. “This is an attack on all of crypto. While other countries are embracing the future, the SEC continues to lash out in fear,” tweeted Michael Arrington, founder of Arrington XRP Capital.

Garlinghouse told Fortune that Ripple is preparing to fight the lawsuit. “I think we have to stand up for all of crypto—and not let the SEC bully the entire industry,” he said, adding “We’re going to be on the right side of history.”

A Ripple statement issued after the news broke said in part that “the Justice Department and the Treasury’s FinCEN already determined that XRP is a virtual currency in 2015 and other G20 regulators have done the same. No other country has classified XRP as a security.”

“The SEC has permitted XRP to function as a currency for over eight years,” the statement continued,  “and we question the motivation for bringing this action just days before the change in administration. Instead of providing a clear regulatory framework for crypto in the U.S., Jay Clayton inexplicably decided to sue Ripple–leaving the actual legal work to the next Administration.”

“This is an attack on the entire crypto industry and American innovation.”

An SEC lawsuit would be yet another parting shot at the crypto industry from the outgoing Trump Administration. Outgoing Treasury Secretary Steve Mnuchin is pushing a proposed rule by FinCEN that would regulate digital currencies. Specifically, the rule would impose onerous restrictions on banks and other “money services business” in relation to so-called “unhosted” crypto wallets.
