reach $500 in 2019 ? I think it is very soon . The market just beginning for the recover.
But in the 2 years forward it can be possible.
LOL did you read the title or not. Question is been asked to know whether this coin reaches 500 USD in this year or not. Well, I can say if the bitcoin reaches the 10k USD before 4th quarter of 2019. Then it is possible for monero to reach 500 USD as well.
Finally speculation may be idea alone not exactly we see such growth in the market.
