The second-largest cryptocurrency by market capitalization continued a two-month surge to crack $1,900 for the first time since late May. Ether was recently trading at about $1,850, about flat over the previous 24 hours as investors continued an early celebration of the Merge, which will shift the Ethereum protocol from a proof-of-work to less energy-sapping, more environmentally friendly proof-of-stake protocol. The token price has jumped more than 85% since dipping below $1,000 in mid-June.
