Polkadot's DOT token price surged over 11% due to its first halving, with annual issuance dropping sharply from 120 million DOT to 55 million DOT, and introducing a hard supply cap of 2.1 billion. Trading volume jumped 300%, reaching approximately $415 million. Meanwhile, the newly launched 21Shares Polkadot ETF (TDOT) on Nasdaq also indicates growing institutional investor interest in the token, though DOT is currently trading nearly 97% below its all-time high.
