The crypto market in the final week of April is marked by a strong Bitcoin rebound, a stalled U.S. Clarity Act in the Senate, and rising concerns over quantum computing as a security threat. Debate also intensifies over XRP’s price outlook, while stablecoin regulation draws focus amid European MiCA-driven growth and U.S. legislative delays. Industry worries grow in South Korea as digital-asset legislation remains held up in parliament.

Warnings are growing that navigation accuracy for aircraft and drones could be disrupted as reference data used by electronic compasses ages quickly. Electronic compasses rely on Earth magnetic field models, unlike GPS, and the World Magnetic Model underpins compass functions in most devices. Earth’s magnetic field is constantly changing, shortening model validity. Concerns are also rising that an end to ESA’s Swarm mission could weaken data reliability, prompting U.S. efforts to develop near real-time magnetic sensing technology.
