In my opinion, the bitcoin has got a good progress so far but still need a lot of time to reach the real goals. To be accepted around the world legally is the ultimate goal of bitcoin. It is possible yet it should take a long time to make it happen. Right now, people trade the bitcoin, some projects accept it as a payment, and it can be used for payment in hotels (in Australia), and many other achievements of bitcoin. These should continue to get more achievement.
