US Securities and Exchange Commission (SEC) Chair Gary Gensler reiterated his stance that proof-of-stake tokens should be regulated as securities. Gensler encouraged token operators to seek compliance, as crypto firms try to avoid the security label and its associated investor-protection requirements. The SEC has increased regulatory scrutiny, recently fining US-based crypto exchange Kraken $30 million for offering staking products. Despite differing views from Commodity Futures Trading Commission Chairman Rostin Behnam, Gensler maintained his concerns without commenting on specific tokens.
