Cryptocurrencies like Cardano, Solana, Aptos, and Polkadot have seen significant declines, with drops of up to 16.8% this week, as a strong economy and rising interest rates shift investor focus to safer assets. Speculation that drove gains in late 2024 is now giving way to reality, highlighting the need for these platforms to demonstrate utility and value generation. The rise of stablecoins may further impact the value of these tokens, as investors react to the evolving economic landscape.
