Ether, the second-largest crypto by market cap, fared even better, recently climbing more than 19% over the previous day to trade at roughly $1,600. Markets continue to look hopefully at the Ethereum blockchain’s Merge transition from a more energy-intensive proof-of-work to a more environmentally friendly proof-of-stake protocol. Other major altcoins assumed various shades of green, mostly on the deeper side, with ETC and SAND up over 13% and 10%, respectively, at one point.
