I just asked myself that when you have bitcoin network, which is as we know "pseudo" anonym. Because of the transaction logs of the network (which are afaik endless), it seems that transactions are traceable.

This is not foolproof though as someone might try to figure out all addresses and cross-reference the amounts and wallet addresses.
