Spreadsheet for sure, I tried using Blockfolio, but the gains/losses never added up correctly.
For those not tracking your trades and profits/losses, what do you do for taxes?! If paying any? I have a buddy whose accountant requires him to note every single trade he does.
Taxes part is also kind of unclear to me, but more interested in how the gains/losses didn't add up. Can you elaborate a bit on that? I'm using blockfolio as well, but didn't see anything wrong with the calculations yet.
