The bullrun by bitcin has given great rise in value to loads of other altcoins and that also includes Ethereum, besides the bullrun from bitcoin, Ethereum is also rolling out an Ethereum 2.0 which tends to solve loads of other challenges that has rocked the blockchain over time. The launch of the Ethereum 2.0 will in no doubt also give ethereum a bullrun and i see $1000 bullrun, so $440 is just the begining for Buterin's innovation.
