BTC's monthly Bollinger Band middle line at 88,800 was broken this week and has now become resistance. Therefore, we should look at the 45-day Bollinger Band middle line, corresponding to 77,250. So, this month, consider starting a position by buying on dips in the 78,800-77,250 range. Meanwhile, the 20-day moving average has formed a rounded top, indicating increasing downward momentum (Figure 3). Its support levels are the lower Bollinger Band at 80,250 and the 52 EMA (around 75,000). Therefore, if BTC breaks below 77,000, the key buying range is 75,000-74,600. Simultaneously buy on dips in all other cryptocurrencies.
