The setup suggests rallies may face heavier supply absorption requirements than in periods dominated by smaller flows.

UK Prime Minister Keir Starmer said political parties will be barred with immediate effect from taking cryptocurrency donations.

Eureka Labs has raised $6.7 million to develop a new Ethereum (ETH) block model that treats blocks as programmable execution environments.
