Is there a way to create a bitcoin transaction map for specific industries
for example how many bitcoins/day month year are into
gambling, retail, darknet/drug/illicit, how many coins are lost etc??
Somehow i think its not possible because thats the point of bitcoin in a way to be ananoymous but there should be some numbers around to put statistic on a map like

But based from your question, I must say that this is somewhat doable as long as you have the BTC addresses of those industries. You can't get all of them but if you work hard and get their respected BTC addresses, you might get some data to work with. We all know that
BTC should be anonymous but we also know that there's a way to track the address of a certain someone through the Blockchain. You may not get all the details that your are looking for but it is possible.
