BTC experienced a spike phenomenon in the early morning, with a low reaching 90,000, which perfectly falls within the previously provided support zone. At this stage, after Bitcoin broke 100,000 yesterday, the market's volatility cannot help but suggest that such movements are likely just to facilitate harvesting operations. For Bitcoin, this stage is not suitable for contracts, as its price fluctuations are indeed too large, thereby containing significant risks.

From the four-hour perspective, the current resistance position is around 99,000. On the support side, it is essential to focus on the 94,000 - 95,000 range on the daily level; however, in terms of overall effectiveness, it is advisable to pay more attention to the support situation in the 88,000 - 92,000 range.

ETH followed Bitcoin's trend in the early morning, experiencing a spike situation with a low reaching around 3,650, which precisely aligns with the support defense position on the daily level. At this stage, Ethereum may continue to initiate a rebound, having already broken through the 3,800 mark. The next step is to see when it can break this year's new high and maintain a strong state. Since there was a rebound after reaching the support defense line on the daily level, the support position can be correspondingly raised, and subsequently, attention should be focused on the 3,780 - 3,820 support level on the daily level, while the upper resistance should first pay attention to the area around 3,950.
