Bitcoin will grow and grow till there is no negative news or govt intervention.But I don't think any Govt likes to lose taxes,encourage underground economy or even fiat currency devaluation.Bitcoin transactions are anonymous and will be harder for any govt enforce rules
But once govt starts to crack whip,bitcoin may come down crumbling.So,invest wisely and be cautious
But I believe that in 2018 bitcoin value were totally achieve the $12,000 or even more .
