I see a nice SELL candle which peaked at $253. Death cross of MA 100&200 at the same time on 4h chart. Chart formation resembles a rising wedge, which is about to fall.
Volume has been falling, and Ethereum was hyped on latest news in crypto media (e.g. "ETH whales accumulating").
While cryptocurrency market, including Bitcoin, was not moving any further up, Ethereum rushed for a new high. This creates warning or a SELL signal.
