Some analyses predict that the currency $DOT might reach a price between $15 - $25 if Polkadot successfully implements its roadmap and increases the projects using the network, parachains, and rollups. There is a possibility that the price of DOT could rise to the mentioned price range or more in the coming few years.
In a more optimistic scenario, if the network witnesses widespread institutional adoption and expansion in the DeFi/AI/Web3 space, much higher prices could be seen by 2030, possibly exceeding $50 in some forecasts.
