$ETH BTC short-term upward move, the price has already touched the 78,100 area, which is the pressure zone of the previous high. Currently running along the upper Bollinger Band, the short-term trend is somewhat strong, but directly chasing long positions carries higher risk. The key is whether it can increase volume and hold above 78,400—if it stabilizes, the upside space opens; if it cannot break through, it is likely to retest, with the mid-line support around 77,778, and the extreme lower boundary at 77,408.

In terms of operation, chasing now is essentially betting on a breakout, while for safety, wait for confirmation: either wait until the four-hour candle closes above 78,400 before going long, or wait for a retest of the mid-line without breaking below before entering; hanging in the middle position is prone to being caught in the middle.
