I really dont understand why bounty hunters immediately sell their rewards. After selling, they keep all the funds in bitcoin. Yes, it might me safer, but dont expect bitcoin price to do +30-50% in a single day. While alts can do that.
Those hunters have every reason to do whatever they want to do with their earned coins; you can advice everyone to HODL but not everyone will heed to the precious advice.
Of course they can do what ever they want. If they are in so much need of fiat - be my guest, sell all the tokens. And tell me when you start selling, because I might buy them for future holding. I will be the first in line to buy bounty hunters tokens. Will try to buy them as cheap as possible at forkdelta.
Take a look on their recent announcement. Partnership with Elrond. Elrond price jumped from - $0,0007 to $0.02. That is x25. That was not just a pump and dump. There is something in this Elrond and partnership with will beneficial for DIA.
