I'm not interested in paying taxes!
I currently use this for analyzing my spending. Helps me plan, and also control how I spend my sats. Ie, how much does my family burn a month? What is essentially? -> Can I quit my job and work on Bitcoin, without putting my family in risk?
I agree that spreadsheet can solve that, but in reality I don't wanna do the work of typing in every little expense into spreadsheet... that's why I actually use Mint for fiat tracking, despite the fact that it's absolutely horrible for privacy. The convenience. I don't need to type every expense. Just once a month review how I spend. I think it's possible to make this convenient and private.
