最新报道:Polkadot's governance has approved a hard supply cap of 2.1 billion DOT, shifting from unlimited annual issuance of around 120 million tokens. The current supply is near 1.5 billion, leaving room for 600 million more. DOT price dipped 5% post-announcement, trading around $4.12, with analysts noting short-term volatility but potential long-term stability. Key support lies at $3.60-$4.20, while resistance levels range up to $45-$55 in optimistic scenarios. The change aligns DOT with scarcity-based tokenomics, aiming to reinforce value over time.
