Recent days have seen quite a few changes in the market. Bitcoin's performance has been quite steady—priced at $89,899.56, with a 24-hour increase of 1.84%. It has repeatedly tested the range between $88,240 and $90,961, with the price remaining at a high level.

From the candlestick and moving average analysis, the bullish alignment of the 7-day, 25-day, and 99-day moving averages remains intact, indicating solid short-term support. The KDJ values are 70.50, 69.84, and 71.82 respectively, with the J value not yet crossing the 80 line, suggesting that while there is upward momentum, its strength isn't too aggressive. In the past 24 hours, inflow of 17,478 BTC was recorded, with a trading volume of 1.564 billion USDT. The trading activity has indeed increased, but it hasn't reached explosive levels; the upward pace remains steady and solid.

In contrast, Ethereum's momentum is noticeably different. The price surged to $3,121.07, with a 4.36% increase over 24 hours, outperforming Bitcoin by quite a margin. The short-term rally between $2,987 and $3,150 is even more impressive. Technically, the moving averages are also bullish, and the price has broken through recent highs, indicating a stronger trend. However, it's important to note that the KDJ indicator has shown some signals—K value at 79.65, D value at 73.09, and J value soaring to 92.77. The J value has crossed into the overbought zone above 80, which could signal potential short-term correction pressure. In terms of trading volume, 370,356 ETH flowed in over the past 24 hours, with a trading volume of 1.136 billion USDT, indicating significant market activity.

Overall, the recent performance of mainstream cryptocurrencies shows two characteristics: Bitcoin remains stable with steady progress, while Ethereum's gains are more aggressive but also carry the risk of a correction.
