bitcoin is far less anonymous than cash. ip addresses are not recorded in the block chain but the public key addresses are. imagine if banks could track the serial numbers on dollar bills.... you can with bitcoin.
So your saying they could track where and to what wallet addresses a specific bit coin goes? But is there a way for them to find out who is in control of the addresses that has it? Cuz if not, it still seems pretty anonymous to me... Or can be, if you want it to.
I agree, its probably not as anonymous as cash but cash can't be instantly transferred to people on the other side of the globe either..
