The chart below is continuing the chart from April 1st: Ethereum ( - 30.4% in May) over Bitcoin ( - 17.2% in May) or the price of Ethereum divided by the price of Bitcoin.

The monthly overview is again showing a downward pressure to this chart. The lower low and lower high for the latest bar is weakness for Ethereum vs Bitcoin. As long as prices are trending lower, Bitcoin is outperforming Ethereum. That is not to say both could fall, and Bitcoin is falling less- or hold up better than Ethereum.
