Heartbeat fluctuates dramatically with price movements, market winds and clouds change rapidly. Only by accurately grasping fleeting opportunities and acting decisively can wealth flow in continuously. On Monday afternoon, Bitcoin rebounded from a low of 65,000 after dropping earlier in the day to around 67,777. Ethereum's trend also followed Bitcoin, falling to 1,937 in the morning and then rebounding to around 2,058.

The 1-hour chart shows a quick rise to a peak of 67,777 followed by a rapid decline and a bearish close. The price was pressured and pulled back from the upper Bollinger Band, with bullish momentum clearly weakening. The high-level stagnation and correction indicate short-term upward momentum is weak. The key support is at the middle Bollinger Band of 66,619; if broken, further downside space will open, and the short-term trend is bearish.
BTC: Suggest shorting near 67,300-67,500, target 66,619-66,000, with a stop-loss at 68,000 to protect the position.
ETH: Suggest shorting near 2,050-2,070, target 1,980-2,000, with a stop-loss at 2,090 to safeguard the position.
