it is absolutely impossible to deny this. Many are inclined to the fact that by the end of 2018 it will be so. However, this should be seen as a short-term drop with a further increase to $ 20,000.
I think that nobody that say what would exactly happen in the future but i think also that bitcoin's price going down to $3000 is hard to believe. Many are waiting for it to go at least $5k and buy so it would pump up again.
