Bitcoin's current upward trend is far from over; the momentum is particularly strong now, with highs continuing to rise, and lows also being lifted higher—an upward trend as steady as an old dog. Don't think that just because prices have increased, it's time to sell; high and low prices are not signals to act, the trend structure and key levels are what matter. As long as the upward trend remains unbroken, even higher prices can continue to rise.

Every time Bitcoin hits a new high, it experiences a small pullback, and each time it can firmly stay above support levels, then continues to rally after just two candlesticks, showing no signs of a major decline or correction. Previously, after reaching a high of 80,738, it pulled back to support at 79,600 and then surged again, breaking through resistance at 80,880 to reach a new high of 81,790; afterward, it retested support at 80,880, confirming the support is valid, then rebounded. It hasn't made a new high yet; as long as it doesn't fall below 80,880, making a new high is only a matter of time.

Currently, Bitcoin faces dual pressure from a flag pattern and the 82,200 level—either break through both together or face temporary resistance. Once it breaks above 82,200, it will head toward around 83,450. Only if it falls below support at 80,880 will Bitcoin truly correct; looking down to 79,600, as long as it doesn't break this level, there won't be a significant correction, and there's no real chance for a sell-off.

Pay attention to key levels: resistance above at 81,405-82,192-83,437; support levels at 80,879-79,804-78,707.

Now, looking at Ethereum, its trend is much weaker than Bitcoin's. While Bitcoin keeps making new highs, Ethereum hasn't even surpassed its previous high of 2,400, and has broken below support at 2,380. For Ethereum to strengthen, it must return above 2,380 and break through the previous high of 2,400 to open up upside space; otherwise, it can only follow Bitcoin's lead.

Ethereum must not break the wedge pattern; if it does, support at 2,340 will not hold, and it will directly retest 2,300, which would severely damage its trend. Future upward movement will then be difficult.

Ethereum's resistance levels: 2,371-2,400-2,422; support levels: 2,351-2,313-2,256.
