Bitcoin anonymity

• Bitcoin is pseudonymous, not anonymous, and
  bitcoins cant just disappear
• It works because every transaction is public and
  visible to each and every other person using
  bitcoin network
• A person is only as anonymous as their link to
  their wallet

Tumbling

• A couple of reddit users realised that the sheer
  size of the heist makes tumbling the coins -
  the normal method of laundering bitcoins -
  impossible, as long as they kept on their toes.
• Someone with bitcoin can send some to a tumbler
  like bitcoinfog, where it will be split into
  smaller subdivisions and mixed with other
  bitcoins from other places, recombining and
  splitting again several times over until the
  whole amount eventually comes out the other end,
  theoretically in such a way that its impossible
  to track.
• Silk Roads in-built tumbler successfully foiled
  the FBI, allegedly.
