Any Comprehensive guide into picking alts?

Hello everyone,

I've been primarily investing in Bitcoin and Ethereum until now, but I'm keen on diversifying my portfolio by exploring the realm of altcoins. While I've attempted fundamental analysis and employed tools like Token Metric, LunarCRUSH, and Skynet to decipher patterns and potential gems, the sheer volume of information and noise is overwhelming.

Navigating through the vast sea of altcoins has been challenging, and I'm striving to develop a more effective strategy for identifying promising altcoins. Is there any comprehensive guide out there. I was looking into following whales transactions, what do you think?

Could anyone share their insights or methodologies on how to find and select altcoins with potential? Additionally, how do you determine the number of altcoins to include in your portfolio for optimal diversification without overextending?

Any advice, tips, or resources you could provide would be immensely appreciated. I'm eager to learn from your experiences and enhance my approach to altcoin investment.

Thank you!
