Not sure how soon it will happen but everyone thinks BTC can down to $2k at the moment.
I think the end of worlcup 2018. BTC will be down to $ 2k.
In my own opinion, bitcoins will not go to $2k dollars because people today are still keep on investing which makes the price to pump up again so by the end of the day, bitcoins will still have the chance to reach $20k dollars.
it is definitely not possible bitcoin can go down to the price of $ 2000. there must be very bad fundamentals to drop such bitcoins. and that too will be difficult, now bitcoin development is solid enough. and prices moved steadily in the range of $ 6500.
