In the cryptocurrency world, the most important thing is to seize the trends. Once the heat is gone, playing around is likely to result in losses.
For example, the peak of L2 hype was during the Cancun upgrade, so you see that ARB and OP have never broken their previous highs; the hottest time has passed, and no matter where you try to buy the dip, you are still losing.
Currently, the hot topics are meme coins and the upcoming major elections. If you catch the trends, you are already halfway to success.
