In an RSA blind-singing based currency, like Taler, a mint who issues the currency can track how much money a particular account sends or receives, but cannot discover the actual transfers. And deanonymizing one transaction does not impact a user's anonymity overall.
In Bitcoin, et al., everyone can track everything about every account at any point in the past. Accounts are pseudonymous and creation is distributed, but deanonymizing a single transaction destroys the anonymity of the whole account. And advanced attacks can be brought to bear on identifying sock puppet accounts.
Yes, RSA blind-sinigng assumes the buyer remains anonymous to the seller, like say buying server time for an anonymous website. Anytime you deanonymize yourself to a seller, like by buying physical goods, then you’re trusting them, this goes for Bitcoin too. In fact, deanonymizing yourself like this is much worse in Bitcoin.
