Bitcoin is currently attempting to break through the major range box boundary at 72,000, while also forming a short-term top. Sell on rallies; you can appropriately establish light short positions between 71,500-72,000. After all, from the weekly chart perspective, the key level is around 65,900. If the breakout fails at this position, it will pull back at least to 67,000 in one step, then verify a bottom divergence around 65,900.
