1. Bounty hunters dump their coin
2. High bonus on Presale phase
3. At the time of listing there is no such development of project which was told.
4. High ICO Price
Bounty hunters have a very small percentage, the token-ico. When they are listed on the encryption exchange, hunters cannot have a significant impact on the price of the marker. Not everyone who received an award for an award immediately sells them. Many who choose, HOLD.
