It is 2017 today and the value of bitcoins is still keep on increasing, I think that the best value of bitcoins will be on 2018 because as of now the value is on $8k and speculations are telling that it will reach $10k in the year of 2018.
This 2017 a lots of investor entering to bitcoin world that's a reason why bitcoin still continue to rise up (growing ) and yes this 2017 bitcoin make a big sound in the whole world it's already reach the 8000$ but for me 2018 will be more exciting year we can see bitcoin hit the all time high 10000$ or more trust bitcoin and continue to hold no matter what happen.
