Anoncoin

Anoncoin is a cryptocoin program with support for I2P darknet. With the addition of being fully tor compatible there is a huge possibility of hiding in plain sight by transferring coins using the darknets only.

This kind of transfer across darknets, exchanges, and "coin mixers" can help you ensure that the coins you received initially either from mining, purchasing, or as payment of services can be fully scrambled and thus not traceable back to your wallet.
