The equivalent of a unit of bitcoin gold to USD is approximately $44.18 at coinmarketcap and that is 5.20% increment from its previous price. I have no doubt bitcoin gold has the potential to do even better. But for it to reach $1000 by the end of 2018, is very unlikely. Because it has to increase by 2,263.46% this year in order to reach this target price. Which is very unlikely.
