where can i find the 30day volume of the top 20 coins by marketcap?

any ideas?

If you find it, let me know.  I asked and asked in forums, spent hours googling, and never found what I was looking for. 

I was hoping to find more than just the top 20.  I was also hoping to find a site that would let me look at 30 day volume for past periods.   I'm guessing that you, like me, recognize that 24 hour volume is meaningless with so much pump-n-dump going on in this space. 

I never found shit.

Yeah, if I knew a little bit more about API feeds, I'd probably just roll my own.  But I don't.

You will need to manually add up all volumes traded by all the alt coin exchanges

We should request coinmarketcap to add this.
