ETH experienced a slight pullback after a high surge yesterday, and today it is rebounding again to test the upper band of the four-hour Bollinger Bands. The resistance here is quite strong, so it’s time to go short; one can short directly around 3800. Watch for a test of the middle band of the four-hour Bollinger Bands, and if it breaks through, we will see it near the lower band, which is similar to last week's BTC movement. Last week, BTC also pulled back to the corner of the lower band of the four-hour Bollinger Bands. However, ETH diverged from BTC last week, but so far this week they are moving in the same direction. Thus, if ETH goes down, BTC will also decrease somewhat. If BTC is just under pressure at the upper band of the four-hour Bollinger Bands, then it is very likely to break through the daily low, and after breaking through, it will consolidate.
