What's the best way to keep track of crypto portfolios? Currently I use Blockfolio, but it doesn't really give me all information I need (e.g. how much total fiat I've invested). I've heard of using an Excel spreadsheet, which seems interesting but I don't have a template or any idea how to start it. Generally, I want a more manual portfolio manager rather than one that is controlled for me. Do any of you guys use Excel or any other way to manage your portfolios?
Definitely
www.cryptocompare.com . Easy interface, all of the necessary information, great control and flexibility. At the top of your portfolio, one of the first numbers you see is the amount of fiat you invested. They will track the changes in price though, I don't know if you want that with your preference for manually keeping track of your investments.
An Excel spreadsheet can definitely work, but if your portfolio grows - it will cost more and more time to find and enter updated prices, time that is worth something and is thus a cost that reduces your portfolio's profitability.
