Is it worth investing in research coins? What should I research? What approach should I take for research and investment?

I am rethinking my logic based on countless experiences of losing money!!!!!!
Buying coins is buying the expected future growth potential.

Understand the project's future development roadmap, development progress, and key upcoming milestones.
For example, if the project has a major upgrade in June this year that you are unaware of,
buying in January means you might need to hold for half a year to potentially see a good increase in returns.
Funds cannot be actively used during this period.
Moreover, with uncertain expectations, a large position can also cause psychological pressure.

If in-depth research reveals the project's roadmap, product development progress, the impact of technical upgrades, the probability of favorable proposals passing, community discussion enthusiasm, etc.,
we can position ourselves to strike when the good news approaches.
At other times, your funds can be used for yield farming, staking, or participating in new token offerings.
Funds can be fully utilized.

This approach is solid, right?
