What BULLSHIT!
RT has been saying Bitcoin is "legal tender" in germany before (couple months ago). That's bullshit of the highest rank, of course. "legal tender" means the "currency" is mandated by law to be accepted by everyone in the jurisdiction as settlement for any debt.
Germany merely categorized Bitcoin as a sort of "private unit of account" and made clear that you have to pay taxes as mandated by the current taxing regime on bitcoin gains and of course VAT if you sell stuff for BTC.
No new law or anything, just sane clarifications (which is good, of course) on how bitcoin fits into the current german tax regime (which it does: you pay tax, no news here).
EDIT: to be honest, the regulatory situation in germany might actually be on the bad side: the Bafin (german banking regulators) have said that Bitcoin is a security and therefore falls under their regulation (they said this years back, btw). They say trading bitcoins (on behalf of others) requires their permission (i.e a banking license, I guess).
