Does it really leave a trial? A dnm wallet is in tor. Its adress is used usually a lot by many people daily. Lets say police know i have send btc to that adress. How do they proof its dnm wallet? They still have no access to my dnm acc etc. I just wonder if it is worth to use bitcoinfog or even put btc through few wallets.
You should at least use an intermediary wallet, like Electrum on Tails.
