From a technical perspective of $btc , the strong support for this main downtrend wave will be at 68,000-70,000, while the bear bottom, based on the method of "carving a boat to seek a sword," is at 40,000-50,000. However, too many people are watching this range, so I believe the final major bottom will likely be around 30,000. Let's wait a year and see if my guess was correct 😁
