Tools to calculate the dollar value for tax

[lavoied]

I need to calculate the dollar value of several thousands transactions (trades, mining and master nodes rewards) in CAD in order to calculate my capital gain. Is there an online database or interface that I could query to get the dollar value (in CAnadian Dollars) for BTC and various altcoins?  Thank you

You can use cointracking.info e.g - they support several FIAT currencies.
like: USD, GBP, EUR, CAD, AUD, NZD ...
You can try it for free (First 200 Trades are free) and check the whole functionality. You just have to register your email (no ID or other Information).

Iam happy with that online tool.

Now that I've had a chance to use cointracking.info all night, I realize that what I need is an API when given the date/time, and a coin, it will return the dollar value at the date/time.
Does anyone know where I could get the historical dollar value of crypto coins through an API?  Thankyou

Damn.Now I realize what pain in the a$$ is to actually pay all the taxes for your crypto revenue+capital gains.
Maybe we need crypto tax accountants that work specifically in the crypto niche.
