Bitcoin is not entirely anonymous, its pseudonymous because each user has a public address that can be traced back to an IP address or an exchange account. The governments want you to use it for money laundering or tax evasion because it's easier to trace than cash.
The IRS has been tracking Bitcon transactions since 2015. Those that made a fortune only to give it back during the bear could end up owing the IRS a small fortune. https://www.coindesk.com/irs-using-bitcoin-tracking-software-since-2015
It's anonymous until someone has access to your IP and exchange account. The advantages of anonymity are being promoted correctly in terms of the ledger.
Hmm, and then there is one other bit to figure. I cannot see how they can consider virtual currency as tangible. So it would be considered intangible property, and something to do with amortization? https://en.wikipedia.org/wiki/Intangible_property
