Lots of factors at play.
1) Very few BCA has been claimed = Very Low Supply
2) Trading on yobit at around - $5 at present
3) Small trades on Yobit showing supply very low.
4) Stocks Exchange again low sell orders = low supply
5) Exrates volume is totally false. They have a buy and sell order every 12 minutes. Look at the history!
6) Larger supply on Exrates is most likely small traders buying now at mega low prices
7) Compare Market cap to other BTC forks - Many not ranked on Coinmarket as supply to evidenced. Work out the price by max number of coins and most are trading at least 10 - 20 times higher.
Mostly hinges on getting listed on OKex exchange once the product is live, then im expecting to see it in line with BTG prices. Massively undervalued at present. As long as the team doesnt ditch the project theres only one way to go. $50-$60 dollars
