If I give my seller a DNM wallet address and he directly funds my DNM wallet, is it necessary to tumble them afterwards?
If not: Let me see if I understood this right. Should I just get him to send the coins to my electrum wallet, tumble them in Bitcoin Fog, send to a new wallet and then DNM wallet? And all of this can be done inside of Tor? Or do I need to go on clearnet and do some steps?
How are you buying your coins? From the darknet or an exchange?
If you don't get coins from a darknet coin vendor then no. If you have the coins sent from the legal exchange vendor directly to your dnm address, then no, you've already done your damage. If you're buying them from an anonymous legal exchange such as lbc cash deposit, then no. You only need to tumble if your name was used to legally buy the coins.
