If you really want to get some alpha on your portfolio you won't get around finance, quantitative trading & applied portfolio management. You can start off with basic online courses/e-learnings like
Yale Financial Markets
(Wharton upenn) Finance & Quantitative Modeling
Patrick Boyle - Applied Portfolio Management
Patrick Boyle - Statistics for Traders (Literally the only channel on Youtube that teaches advanced Finance)
Dodge everything that has "technical analysis" or exclamation marks in the title, or edgy thumbnails with screaming faces. The technical analysis all of the crypto youtubers are talking about is pseudoscience with no scientific background at all.
Learning all of this, reading a ton of books, learning finance, eventually learning programming, all of this will take a lot of time and is not easy at all. On top of that you also need to know the tax legislation in your country in regard to crypto, knowing exactly what is considered a taxable event and what not. Depending on the laws, this could heavily impact your risk reward ratio while trading crypto.
As others already said, you are better off just holding onto your investments for a good amount of time. You save your own time, your nerves and probably taxes.
