How many Bitcoin Wallets were ever assosiated to any form of transaction?
Note, there is difference to "How many Bitcoin Addresses hold Bitcoin", which seems to be around 81 million. This number does not include Addresses that have received some Bitcoin, and then sent it all away somewhere else. I am looking for the number that includes these cases.
Blunder in the original question. I meant to say "Addresses", instead of "Wallets". Thanks u/Calius1337 for pointing that out.
