The question is in the title. Everyone pretty much knows where to go to see current market cap valuations and weighted average prices of altcoins against bitcoin and fiat... but where are the favored places to go to look at the history of market caps?

Why?
It might be relevant if say back in April Bitcoin was a little over 30bn and now its over 65bn to consider how the market might react to news.

What do youuuuuuuuuuuuuuu think?

Thanks for the read and consideration.
