$ETH doesn't need me to say it; it's evident that this round of increase is much stronger than $BTC. After pulling back to a key resistance level, it has come back to around 3940. There is a significant amount of short positions accumulated around the upper high of 4000.

Personally, I think it's fine to take short-term short positions, but if $ETH is to break through 4000, there will be a wave of extreme rally. Both those who chase the rise and those who short will enter the market, and it is very likely to break through the 4100 high from December 24, completing a new round of reshuffling.

Retail investors have almost sold off their $ETH, and the majority of the market share is now held by institutional buyers.
