I know that almost all of the exchanges have fake volume. I will not use this data for trading, and todays's datas are not important for me, I need historical data. I am trying to make an analysis for market and volumes of exchanges. I am not looking at coins.

So I need historical volume datas of exchanges.

I am really chocked because the answers shows that we are not knowing anything about the historical volume data of exchanges. We are saying that all the things are recording on blockchain and market, and this is fully digital sector, BUT we do not know anything about history of exchange volumes. AND people thinks that this is not important. Really unbelievable.
