The current trend of the market is too closely linked to the US stock market, but once it reaches around 81000, BTC becomes slightly stronger, indicating that there is still support here. Last night during analysis, BTC was around $81700, with a 4-hour MACD dead cross and RSI entering the oversold zone. I judged that there was a short-term pullback demand, but it has not yet been confirmed to stop falling. Looking at it again today, BTC remains around $81900, temporarily holding the support of $81000, indicating that the selling pressure has eased, but the rebound is clearly insufficient. Technically speaking, KDJ is still at a low level, with trading volume continuously shrinking and prices running below the short-term moving average. This is more like a weak consolidation after a decline, rather than bulls regaining control. At the macro level, the sustainability of the Nasdaq rebound still needs to be verified, and the Federal Reserve's interest rate hike at the end of the month has increased market uncertainty. BTC currently lacks a catalytic factor for sustained upward momentum. My judgment is still cautious: for the rest of October, BTC is likely to maintain a volatile and weak pattern. Pay attention to $81000 below, if lost, you may test $80000 again; It is necessary to regain a stable position above 82500-83300 US dollars in order to improve the short-term structure.
