It is quite risky and can lead to regret. FOMO can drive us to anxiety for some immediate action, without any research, just the certainty that any coin can reach high gains as long as the purchase is made as quickly as possible.
I think altseasons are governed by certain narratives absorbed by a part of the market, which leads a series of projects to stand out more than others. In 2021/2022, DeFi took over due to attractive passive income proposals, leading tokens to explosive valuations (and million-dollar thefts through vulnerabilities in their protocols).
The next altseason seems to count again on DeFi, maybe with greater focus on those offering liquidity to large traditional institutions, with low fees and interoperability across different blockchains. I believe that DeSci and DePin are also interesting narratives due to their applicability to "real" problems and mass adoption.
I’m not sure if your intention is about quick trades or longer-term holding; in any case, I suggest looking for reasonably reliable sources where you can update yourself on the most disruptive developments in the market and navigate projects until some of them convince you through their narrative to the point that holding is not such a strenuous task.
DeFis can be interesting in this respect because of passive income, which would guarantee you some immediate return and a gradual reduction of exposure to risk. DePin projects with a large user base may offer a higher probability of organic growth and sustainable long-term appreciation. There are DeSci projects already showing good results in the search for new ways to deal with pathogens, projects that can even be directly invested in via their own tokens on launchpads such as Bio.
In short, value your hard-earned money and position it in the best possible way, as we may be facing a strong altseason.
