It's true. The blockchain is at best pseudoanonymous. If you are careful about how you get your coins, and use a high latency mixer (which don't exist as far as I know, but can be faked by multiple runs through a low latency mixer) and take your profits out slowly, you can make them quite anonymous. While they are a richer stream of data that a purely cash business, they don't have the same hassles (mostly physical size and security issues) as cash.
