Bollinger band is an important indicator. The price tends to stay within the band range. When the weekly chart of #BTC is examined, it is seen that it does not like to be out of contact, except for Bollinger. The current view shows that in case of weekly closing at this level, the Bollinger upper band level will be around 87,600 USDT. In other words, a situation of no contact will occur. Should we be ready for corrections in the bottom due to #btc?!
