Bit-coiners used to love bitcoin because it was (supposedly) anonymous, untraceable, and fungible (which they took to mean "I can spend my bit-coins, no matter how I got them").

But recently I have seen several posts where bit-coin peddlers praise it for exactly the opposite reason: that the history of each bitcoin is open to all. E. g. from this article:

For real estate agencies like JUST-SOLD or even the authorities, information regarding source of funds are often difficult to verify or disprove. With a physical cash deposit to a bank account, it is almost impossible to prove the origin and with bank transfers it is only the ‘one step backwards’ that can be traced. Joosep Vahtras explained: “Since banks operate with closed ledgers a great amount of resources are required for obtaining the information in midst of the bureaucracy and customer privacy. In comparison, Bitcoin as a payment system uses open public ledgers that are transparent and easily accessible for everyone.”
