As for when altcoins will surge.

1️⃣ Early Bull Market: Bitcoin rallies, and altcoins lag behind Bitcoin. Some altcoins might rise a little, some just tread water, while certain trending sectors will keep pace.

2️⃣ Mid Bull Market: Some strong altcoins and trending sectors will complete their bull market gains ahead of time, and the old mainstream will start to move as well.

3️⃣ Late Bull Market: This is also the phase when altcoins surge the most, leading a group of altcoins to reach new highs, marking a widespread altcoin rally.

In short, every market cycle is led by Bitcoin, except the late bull market, which is led by altcoins.

The rhythm goes like this: Bitcoin, altcoins, and then altcoins.
