On the 4-hour K-line cycle of BTB, since the bottom rise at 74500, there is a clear upward support line. This upward trend line is too steep. The big coin has risen from 74500 without experiencing a pullback; both adjustments have been horizontal instead of downward. Today, the big coin broke through the weekly consolidation pressure line and set a new high. The upward momentum is already a bit weak. After setting a new high here, do not have too high expectations for short-term targets (observe the closing at 8 AM tomorrow). Once the market shows a short-term bullish profit pullback, ending the upward trend since 74500, the profit-taking adjustment is likely to break the 92800 support, testing around 90,000 or seeking support in the 89,000 to 90,000 range.
