Polkadot's investment in tech innovation and performance optimization, like Polkadot 2.0, has the potential to boost DOT's price. It improves scalability and resource allocation, attracting more projects and users. Solana's efforts, such as the planned TPS - boosting system, also enhance its competitiveness. If these lead to increased adoption and usage, SOL's price could rise. However, market conditions and competition also play roles, so the exact impact on price appreciation is hard to predict.
