【Crypto World】BTC market has been quite turbulent recently. The price once dropped to $86,673 and is now hovering around $87,208. Trading analyst Josh Olszewicz issued a warning — the risk of a pullback is building up. He pointed out that there are signs of a bear flag pattern in the trend, which typically indicates downward potential. More notably, on the weekly Ichimoku cloud chart, the current position also reveals some signals. There's also a timing factor to watch out for: at the end of December each year, many investors engage in tax-loss harvesting to optimize their tax situation. This creates a wave of artificial selling pressure in December. So, recently, it's important to consider not only technical analysis but also seasonal factors that could increase selling pressure.
