Stimulated by geopolitical news, BTC surged 3000 points in the evening, reaching around 71800 at best, but this is purely emotional speculation and bullish momentum has weakened. From a technical perspective, the 4-hour chart pierced above the BOLL upper band then pulled back, with heavy selling pressure at highs and no reversal trend structure formed. Operationally, we remain focused on shorting at high levels, following the trend is the way to profit!
