In my opinion future of bitcoin us uncertain. It could be bright or dark. Bitcoin is just one of many cryptocurrencis and it is heard to embrace. Few time ago it hits 6000$. Many developed countries including bitcoin in their payment system. And in some country bitcoin academy and camping are also initiated. Nowdays bitcoin investment is on top so many investors invest their money in it. These things makes it popular and makes its future bright. In other hand many countries government declared bitcoin is illegal due to some criminal issue and other thing so this thing makes its future dark
