Gotta agree with the other people here, I see this on more than one forum every year, 2015 year of bitcoin! Gonna be big this year!
And then when it's not, it stays the same, maybe a few more businesses incorporate BTC into their payment systems a new thread is opened saying 2016.
But who knows you may be right, and then you can say 'I called it! Look at my thread I posted'
Ok, Just consider the following please, If 2015 or any other year had been "The big year" then this would mean that nothing better can happen which is not true and as the future is not known then it does that reference to each year could be "The year" , So say that every year will be better help to maintain a sense of hope and challenge to call in some way which translates into greater interest.
Can you imagine to live in a world in which the better thing has passed?
Its not only applies here, always try to be optimistic and think that next year will be better than today.
Edit: For last, remember also that sometimes can be a good year in some sense for some peoples and not for others. But fortunately there are more years.
