This is going to sound embarrassing i've been buying and selling bitcoins for like over a year now and i've lost track if i'm currently losing money or up any money... i suck with math and there's so many pages of transactions is there a program to import everything into it and see lol.... (yeah this is pretty bad hahaha) any help would be appreciated i use coinbase...
Just look at total: Total USD deposited and withdrawn, then compare that to your current BTC value
Otherwise:
http://www.coinreporting.com/ lets you import your trading history and shows nice data
