The journey of bitcoin from 2009 to 2017 is very interesting. Although the stories of individuals(investors) are very interesting and motivational that how they initiated and what problems they faced at earlier stages.
In 2017 the number of businesses accepting bitcoin continues to increase. Where you see the bitcoin in 2018?
I think it will continue to rise and people would start to adapt and accept it. As of now, bitcoin might even reach more than 20k USD before ending this year but I can tell right now that bitcoin became really popular and its value is truly something that needs to be written in the world's history. I think 2018 would be a tough year for bitcoin because there will be a lot of corrections, forks and I think overcoming those challenges will make bitcoin much more stable cryptocurrency.
