Could you please explain in detail how one can create a crypto tracker in Excel? I'm relatively new to both cryptocurrencies and Excel and would appreciate a step-by-step guide. Specifically, I'm interested in tracking the prices of various cryptocurrencies, their market capitalization, and any other relevant metrics that might be useful for investors. I'd also like to know if there are any ready-made templates or plugins that could simplify the process. Additionally, are there any specific Excel functions or formulas that would be useful for such a tracker? Thanks for your help!
