on anonymity. (Sorry if I'm jumping ahead)
Is it possible to be truly anonymous in the purchase of BTC's? I've read that you have to provide some sort of ID to purchase prepaid debit cards so wouldn't they be traced back to you?
I've also seen a website that finds local BTC vendors in your area, but you have to register with the site to get their info and communicate with them. Even if you found a vendor locally, wouldn't there still be a trail if you paid cash for BTC's?
Does a "tumbler" break any kind of trace back to the original purchaser?
Thanks in advance.
