My answer is no. Firstly, because bitcoin price is unstable, one it can be $600 and next day - $600. Secondly, there are no places where I can spend bitcoins - i would have to exchange to my local currency. So, I prefer to get sallary in Euros, and I think situation won't change in nearest future.
using bitcoin for a short period of time is indeed incomprehensible, but if bitcoin is used for long-term investment, then the result will be felt. bitcoin was created to compete with other currencies, bitcoin does not aim to impose other currencies.
