I guess it's going to become popular in two years or so, unless another 2008-like (or even worse) crisis will take place. We've seen a lot of spikes in the price of Bitcoin and I have only a few friends who know what Bitcoin is, and now they don't know if they should invest in it or not. If everything goes well, by the next winter we'll make another price history again.
I also hope that bitcoin could become popular in the near future but we can only hope that once again the decisive bitcoin be popular is the adoption of many people it can be accelerated with you also helped, such as invite your friends to join
Being users of bitcoin I think we should be positive and have total faith in its ability and looking at the present development in bitcoins I don't think we need to worry about its future.
