I use Circle for buying btc. I know there have been some issues recently with Circle shutting down accounts after tracking users' bitcoins to DNMs. I don't know to what extent Circle is capable of tracing the btc, or if any bitcoin tumbler is safe to use. I know bitcoinfog is pretty good, but has been selectively scamming people recently, so I don't want to use that.
Any suggestions to avoid getting my account shut down?
