Bitcoin has currently rebounded to a high of 73,900, but the bullish momentum is weak, only half of the bearish momentum. The estimated rebound space is limited, with a maximum rebound to around 74,500. The weekly-level 5th wave downtrend has already started. Once the rebound is in place, short $BTC and $ETH. This is the main strategy at this stage, with an initial target price around 60,000. In a bear market, seize the opportunity to short at highs. This is a definitive money-making opportunity in a bear market.
