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?
Regarding "businesses accepting bitcoin continues to increase". Several companies including Microsoft who took payment by bitcoins earlier refused it. Giants like Amazon and Facebook are showing an interest in cryptocurrencies. I think that they will create their own successful coins. They have everything for this.
