I just re-read The Intelligent Investor. Its an old book but still relevant in the age of crypto. The idea is to find a great undervalued company and invest. Ignore the day to day price or what the "experts". Just hang with it while it is still showing solida growth. Never invest in something that you wouldn't plan on staying with it for at least 5 years.

This strategy works with crypto. It encourages hodling and it requires you to understand the project before buying. I know so many people that will buy an alt-coin solely because it went up 100% in the last seven days.
