2016 is the best year of bitcoin, because the price of bitcoin increase up to 2 times. For 2017, i don't think it will be a year of bitcoin. Because there is no big news on 2017, but we don't know though.
Every year was great in bitcoin but some of the event happens like bitcoin halving in 2016 and the result was great because the value of bitcoin is increasing and if 2017 come and the price would be stable i think we can say that 2017 will be year of bitcoin too.
yeah, every year was great in bitcoin and you are right that bitcoin halving in 2016 it result is very good and bitcoin going to rise up it price to much faster and i am also sure that 2017 will be year of bitcoin.
