Ether tops $4K mark

Bitcoin rival Ether, the second-largest cryptocurrency in the world, soared past $4,000 per coin for the first time on Monday.

Ether, which is the native cryptocurrency of the Ethereum blockchain, saw its price climb more than 5 percent Monday, Coinbase data showed, and trade at about $4,100 per coin.

It pared some of those gains and traded at about $4,040 per coin later in the day.
