最新报道:Polkadot has set a permanent supply cap of 2.1 billion DOT tokens, with approximately 1.6 billion currently in circulation. The remaining 500 million tokens will be phased in over 135 years to prevent market oversupply. The issuance rate will drop from 7.4% to 3.3% by March 2026, increasing token scarcity. Following the announcement, DOT's price rose 1.1% to $4.03, while trading volume decreased by 40%. The community views this move as a bullish catalyst ahead of Polkadot's upcoming 2.0 upgrade.
