I think bitcoin is one of the most valuable cryptocurrency this 2017. Maybe bitcoin's price will increase more and its value will be higher than last 2016.
It is already sir the value of bitcoin last year was already increase by 50% and i think before this year end the value was double as the value last year.
That is why much better to keep bitcoin until 2017 ends.
Not only for 2017 but for more years to come, the value has increased dramatically and it will continue since
we have break the ATH that's why it keeps rising now. More good news will come and we will be surprise.
I agree with you, this year and for the income years the price of bitcoin will grow even bigger and a lot of people and countries will embrace bitcoin as their another currency and that is how the bitcoin will become stronger in the market and i will not be surprised if the price will reach at least 5000 USD before the 2018 year ends.
