No exchanges in 2009? Im talking about 2010! You said you tried the website i brought up... all i said was i tried punching in march of 2010 but no price is available for this date! It says cannot fetch price for given date!
Like I said no exchange at that time according to the history I already provided you a link about the history of Bitcoin.
So theres no chance that you can fetch data from march, 2010.
The only known exchange was started year 2010 is MT. Gox but it launched July, 2010.
You are correct. Besides this in general what can happen is that a website simply does not have data that is that old. Coingecko for example has this price as ATL:
All-Time Low
$67.81 169.57K%
Jul 06, 2013 (about 12 years)
Have you check CMC it has the price data July, 2010?
I confirm that it does.
All-time low
Jul 14, 2010 (15 years ago)
$0.04865
+236390612.58%
For basic calculations you don't need a calculator robertcarlyle, you can just use the price data from anywhere that is available like CMC.
