"Bitcoin is just another fiat" - well everything used as money is fiat - Gold only has value because some people want to hold it but in itself it is rather useless and far less practical than BTC.

BTC is probably nearer to Gold in reality than to national fiat currencies in the way it behaves - independent of governments and easily exchanged among individuals.

Back to topic - BTC is increasing rapidly against fiat currencies because people are becoming aware about its existence and the smart ones see it as a real opportunity to get in at a relatively early stage of something big.

Sure the Cyprus fiasco confirms to those who were unaware how incompetent governments are when it comes to money - and many see BTC as a viable alternative.

I'm not sure about the FinCEn stuff - BTC is global rather than US-based.

Having worked with governments I see no danger that many governments will get together against BTC - they find it almost impossible to get together to agree about anything much as a common aim - systemically BTC is safe from their meddling - and that is another reason why BTC has a great future - it is a people's not a government's currency!
