Recently, emerging cryptocurrencies like Solana and Avalanche have experienced wild price swings. Solana, designed for large - scale applications, has seen some expansion in use cases such as in the Solana - based DeFi platforms and NFT marketplaces. However, whether it fully supports the price surge remains debatable. 

Avalanche, with its sub - networks for various applications, has potential in areas like decentralized finance and enterprise solutions. But its application adoption rate might not be on par with the drastic price movements. In general, while their application scenarios are growing, more time is needed to determine if they truly underpin the current volatile price performances.
