The market for altcoins during a bull market typically goes through the following stages:
Stage 1
The coins that often see the largest increases are those you have never encountered before, or even completely unfamiliar coins.
Stage 2
At this point, the coins that are rising are often those you have previously held, but unfortunately, you did not hold on and missed the biggest gains.
Stage 3
When you can no longer endure it, you decide to switch positions and chase those coins that seem to have started rising. The result is that the originally popular coins immediately retrace after you chase them. Meanwhile, the coins you just sold suddenly start to soar right after you switched positions.
