In the next 20 days, there are several possible scenarios regarding the trend of Bitcoin (BTC) and altcoins, as follows:

1. BTC breaks through 90k and establishes a bottom, accelerating to above 100k: This scenario indicates that BTC has formed a short-term bottom above 90k and successfully breaks through 100k, then enters a phase of rapid growth.

2. BTC oscillates between 90k-100k while altcoins strengthen: BTC may oscillate within this price range, leading to funds flowing into altcoins, pushing altcoins to perform better than Bitcoin.

3. BTC oscillates between 90k-100k, altcoins perform weakly: Similarly, BTC oscillates within this price range, but at the same time, altcoins perform relatively weakly, possibly due to the market's greater focus on Bitcoin's dominance.
