I believe Ethereum is currently doing an irregular flat structure 3-3-5. This means that the high of the second corrective wave labeled B, exceeded the top of wave (1). This is particularly nasty because it gives a false hope to investors that price is going to keep rallying to new highs when it is about to fall back again. However a particularity of the irregular flat is that the excess over wave (1) is saved on the downside. Instead of going all the way down to 2400 like a regular flat would do, it may stop around 2500 instead because it is of the "irregular" type.
