币界网报道：Major investment firm VanEck issued a terse one-word response — "Unconstitutional" — to the U.S. Senate's newly proposed crypto oversight legislation that would classify most digital assets as securities. The Digital Asset Anti-Money Laundering Act, introduced by Senators Elizabeth Warren and Roger Marshall, aims to impose strict banking-style regulations on crypto firms including exchanges and wallet providers. VanEck CEO Jan van Eck criticized the bill's broad securities classification approach, arguing it contradicts existing case law and could stifle innovation. The legislation would require crypto miners, validators and network participants to comply with know-your-customer rules typically applied to financial institutions. Industry advocates warn the bill's expansive definitions could effectively ban decentralized finance protocols and push crypto development overseas.
