1) if any dev want to avoid dumpers then they must limit bounty participants, the limit the participants they better ,if a bounty only request 300 participants at highest and the 300 became a dumper it won't hurt ,unlike 2000+ participants
2) devs should forget bounty when still on ICO ,allow bounties after your project finished ICO successfully and make your project is doing great before allowing bounty
This are just ideas ,if you have anything better please drop on here and let's share.
Maybe that's enough. Maybe enough already humiliate hunters? the hunter gets 1-5% of the total volume. You understand this amount is not able to bring down the price of a coin. Let the projects change their investment policy. Together with the bonus program which often amounts to + 50% of coins, let them significantly increase prices in stages.
You constantly blame the hunters. Only the problem is not in us but in companies that do not fulfill their conditions.
