The total marketcap from christmas 2016 to 2017 has gone up more than 13x. If this trend continues, which is likely, it could go up even more by the end of 2018.
Most of the top ten coins have gone up more than 10 times, even more than a 100. XRP was 0,006 cents a year ago. If verge only gets to the marketcap that Cardano has today, then Verge will be at 0,76 cents a piece. I think this is a realistic setting for Q1.
If the marketcap continues to grow, and Verge reaches the marketcap that BTC has today (assuming btc and other top 20 alt marketcap continues to grow as well), than verge will be at 19 dollar a piece. A dream come true but little unrealistic in my point of view, won't say it won't get there but there might be a better coin in the mean time.
Verge price will be very volatile though with all these millionair whales who got in early
