Grayscale believes that the evolution of US debt would favor Bitcoin, Ether, and Zcash. These three cryptos could benefit from significant demand for assets independent of fiat currencies.

The crypto still suffers a decline of nearly 27% since January and remains significantly below its 2025 peak.
