Gu Jingci: Bitcoin/Ethereum is about to plummet on July 21st.

Bitcoin saw a significant intraday surge, forming a catch-up rally, currently around 66,700. Those with short positions can add to their short positions. For Ethereum 1, hold short positions patiently as the price rises and wait for further declines. As mentioned many times before, if Ethereum and most altcoins don't follow Bitcoin's upward trend, the rally is likely nearing its end. Conversely, if Ethereum and altcoins remain relatively stable during Bitcoin's decline, they are likely to continue rising. Tonight, pay close attention to Bitcoin's previous daily high of 67,300, a level we've repeatedly highlighted. For Ethereum, the 1950-1980 range remains a resistance level; there are too many trapped positions from the previous period, and they won't be easily unwound. Trading suggestions: If you entered a short position in Bitcoin during the daytime session, add to your position at the current price of 66700. The average price will be around 66200 to 66300. Wait patiently for the price to fall, with a short-term target of around 64000. Hold your short position in Ethereum at 1930 patiently, with a short-term target of around 1850. Place additional orders at 67500 and 1980. A break below these levels will trigger a new round of sharp declines.
