United St Securities and Commission, or SEC, chair Gary Gensler has doubled down on his “Wild West” analogy for cryptocurrencies, calling stablecoins instruments for gambling at old-timey casinos.

Speaking to Washington Post columnist David Ignatius on Tuesday, Gensler said most projects in the crypto space dealt with securities that fall under the regulatory purview of the SEC, while the Commodity Futures Trading Commission, or CFTC, was better suited for enforcement for others. The SEC chair described the authority of both agencies as “robust” but said there were gaps in the coverage, particularly for stablecoins, which “may have attributes of investment contracts.”
