Bitcoin prices have never been so low this year. Prices were down to 5,826.41$ (Jun 24 2018 16:04:00 UTC). Many advisers say that at the end of the year it will hit 30,000$. The market is seeing more than the fall from the price rise. Imagine when the speculation will end?
Although the price of bitcoin may still eventually reach $30,000 by the end of the year, I still wouldn't advise you to believe or have hope on predictions like this.
We have, since the beginning of the year, had so many predictions concerning the price of bitcoin and most, if not all, of them have been false. So many people predicted that the price of bitcoin will strike $18000 before the middle of the year and here we are now with nothing to show for it.
The price of bitcoin is very volatile and as such no one can accurately predict what will happen to its price.
