I googled "darknetmarkets" to get here, and the url of the first hit was https://pay.reddit.com/r/DarkNetMarkets/ Is this correct? or should I use https://www.reddit.com/r/darknetmarkets

I bought bitcoins through a exchange, which I had to give all my information to. I then transferred it to MyTREZOR web wallet. It seems my identity is still very connected to my coins. Should I tumble them? Is there a wallet I can transfer them to that will disconnect me from the coins? Or is straight from TREZOR "safe", assuming I do everything else correctly. I want to err on the side of caution here.
By now it doesn't matter any more, as both links use/support https.
As for the other question, try searching for "helix light" - it is free of registration, fast and has a 'process'-page you can see what's up with your transaction.
But if you just want to cut the connection, you could also transfer them to an offline-wallet like electrum, I guess.
