The altcoin season from 24 years ago had several notable characteristics:

1. In the past, when BTC rose, ETH would follow, and during ETH's rise, many altcoins would follow suit, occasionally with some altcoins leading ETH in strong surges of over 10 times. However, it is now clear that after BTC rises, ETH does not follow, and this has long been evident.

2. After the bull market began in 2021 with BTC and ETH, there was a notable rotation effect in altcoin sectors, where after public chains rose, DAOs would rise, and after DAOs rose, NFT sectors would rise, and so on; although there was no sector rotation rise in 2023, there were still some conceptual sectors that rose in sync, such as L2 and AI sectors.

3. The previous altcoin seasons were filled with numerous coins that had a continuation of upward trends, essentially following three types of upward patterns: the first is a small step rise along the moving average, making you hesitant to chase, and if you do, you quickly want to take profits; the second is a dramatic rise and fall, rising rapidly, but during corrections, it would flash crash by 30% to 50% and then quickly rebound, crushing highly leveraged long positions; the third is a zigzag pattern, with consecutive rises and consecutive falls.
