According to CoinMeta, although the price of Bitcoin broke through $80,000 last week, this week seems to be leaning towards a bearish trend, with the current price having fallen back to $77,976, which is about a 5% decrease from last week's high of $82,281. Analysis suggests that this pullback may indicate that the bullish momentum of the second half of August has ended. According to CryptoQuant data, Bitcoin ETF has recorded a positive net inflow of approximately $21.9 billion in the past 30 days, after experiencing an overall negative inflow in the second quarter. Analyst Darkfost mentioned that the current key price range is between $72,000 and $73,000; if it falls below this range, it could put pressure on ETF, prompting them to sell more Bitcoin. Although market sentiment remains in a greedy zone, macroeconomic factors have a significant impact on Bitcoin prices, especially the intensifying conflict with Iran and rising oil prices, which may have a negative effect on investor sentiment.
