Looking at the recent Bitcoin chart, it's really interesting. The current K-line pattern is strikingly similar to the top trend in 2021, which is worth a close look.

Compare the two charts side by side and you'll understand. Both show an initial sharp rise, followed by a period of sideways movement. In 2021, it was a surge followed by weakness; now BTC's performance is quite similar — multiple attempts to break through the upper trendline have failed, as if an invisible hand is pushing it down each time.

From the weekly chart perspective, a classic ascending wedge pattern has emerged. This pattern often signals a reversal, especially when the price struggles to go higher. Historically, ascending wedges frequently indicate a turning point from bullish to bearish. That's exactly what happened in 2021 — after a stagnant rally, a sharp decline followed. The current trend seems to be repeating this old script.

Momentum indicators are also issuing warnings. On the weekly chart, the energy behind this recent rally is clearly waning, lacking the support for new highs. Many refer to this phase as a "rally retracement." If a reversal really occurs, it could be the last chance to escape.

Of course, this is purely based on technical pattern analysis; the market's ultimate direction depends on capital flows and macroeconomic factors. But this similarity definitely warrants caution.
