Bitcoin formed a golden cross on the hourly level last night and rebounded, but the rebound was weak, with the high point falling back near 116000 without stabilizing. The four-hour chart broke below the middle Bollinger band, testing the support of the 60-day line. The daily chart pattern has not broken below the middle Bollinger band and the life line. The daily chart maintains a bullish trend, but the four-hour level is still in a correction phase.

Ethereum's daily chart tests the support near the life line, with a weak rebound. The daily chart also pulls back to the support of the middle Bollinger band, focusing on today's small cycle changes. Only a golden cross on the hourly and four-hour levels can drive the market rebound.
