Take a look at this chart. The BOLL indicator is particularly useful for grid trading in a wide range of volatile market conditions. At present, as long as BTC does not break 90000, there is still a chance for a bull market no matter how much the knockoff market falls. Even if there is an adjustment in a trend market, it usually takes about 3 months. Starting from 12.18, it will end in mid March. If it enters the oscillation range from 11.19, it will be in mid February. Just plan for another month of oscillation. At this stage, there is really no need to be overly optimistic and pessimistic. It is normal for the market to repeatedly rub and consume patience and confidence before breaking through. I firmly believe that there will be a big market trend in the first half of the year, with a fast start in late February and a slow start in late March. Once it starts, it will be a three-month bull market.
