Bitcoin's current trend is concerning, with the daily MACD approaching a death cross signal, and a bearish atmosphere prevailing. It is expected to remain weak before the meeting, with considerable downside potential.

However, from a short-term perspective, around 89,500 has formed a certain support level. This is a secondary bottoming process; as long as it does not break below this level effectively, there is no need to be overly pessimistic. The previous long positions at 90,000 and take-profit at 91,500 have validated this support, precise to the penny.

The upcoming trading strategy is as follows: the current decline remains within the secondary bottoming range, so consider small positions to participate in the rebound. If it slightly breaks below 89,000, stop-loss immediately; the risk-reward ratio remains acceptable. It should be noted that the rebound strength during a secondary bottoming is usually not as vigorous as the first, so if the risk seems not worth it, observing is also entirely reasonable.

If this level is truly broken, the next defense line is in the 86,000-87,000 range, where a steady rebound can be safely played. Continue holding long-term short positions, with a target around the end of January.

The trend for ZEC is relatively clear. The support at 400 has been validated as a take-profit level. Now, with a rebound to 450, some traders have already taken profits. This decline around 400 marks a perfect ending point. If the next rebound approaches 530, it would be a good time to re-establish short positions, which is the most prudent choice. Although 470 is a short-term minor resistance, it is less significant compared to the pressure at 530.

WLFI has recently performed astonishingly. There was an abnormal surge in the short term, followed by a swift counterattack from the bears, with the decline rapidly expanding. The short position at 0.186, initially intended for long-term holding, has already yielded a profit of 10,000 yuan. Given the rapid recent decline, it’s better to take profits now rather than hold uncertainly. Wait until mid-January to see if a new rebound opportunity arises, then re-enter.

Overall, whether it’s mainstream coins or small-cap tokens, the trading ideas for BTC, ZEC, and WLFI are clear. Key resistance levels should be used for short positions; with the right strategy, opportunities can be confidently seized.
