what about privacy?

since all transactions are public, you can just go through the blocks and trace an account to individual / groups

well really obvious ones, like for example, a account with 10,000 Bitcoin per month revenue, there are only so many organizations capable of that, and through process of elimination and probably other tracing techniques, you can find out the EXACT amount of bitcoins any individual/group has.

and not only that, you can deduce who these individual/groups do business with and how much is transacted.
