Year-end market trends are often accompanied by shrinking trading volumes, and the past few days have been no exception for Bitcoin and Ethereum — volatile but relatively weak, yet bottom support remains.

Looking at Bitcoin, the $87,000 level is a key point. If the price holds here, there’s a chance for a rebound to test $89,500, and further possibly push towards the $90,000 round number. Conversely, if it breaks below $87,000, the correction pressure increases and caution is needed.

Ethereum is also worth paying attention to. The $2,900 support level, if held, could lead to a rebound to $3,000, and a breakout might see it reach $3,050. But if $2,900 breaks, the price could test lows around $2,850.

From an operational perspective, Bitcoin has a potential long opportunity in the $86,800 to $86,500 range, targeting $88,500 to $89,000; Ethereum can also consider buying low in the $2,900 to $2,850 range, with targets around $2,970 to $3,000. Holiday market fluctuations are not large, but opportunities always favor those who are prepared.
