I believe every year is a year of the bitcoin, as long as it's growing in value, and more people adapting to it, i believe it's a success
In my opinion, people think 2016 is the year of bitcoin because the value will continuously be going up, and so far it hasn't disappointed us because it is going quite what we expected. Although there are also many people who believe 2016 is the pioneering year, 2017 will be the most progressive year for bitcoins.
Yeah and I think the year of bitcoin has just begun with recent price rise and the coming months would be more exciting and great surprises for the users of bitcoin.
