For the Americans who wish to stay as anonymous as possible whilst purchasing bitcoins, I suggest to you these steps:
Acquire anonymous PayPal account (this shouldn't be too difficult for those already seeking anonymity.)
Locate your local CoinStar machine. You can deposit cash directly into your PayPal from these machines, charging $3 for upto $300 and 6$ for above 300.
With your money in your anonymous paypal, create an anonymous LBC account. Initiate a trade with a high volume PayPal seller with a quick turnaround time.
Tumble your coins out of LBC wallet. Tumble coins into your DNM.
Maintain proper networking OPSEC throughout, including the PayPal phase.
