that's right, the project will be dead at the very first day of its circulation in the market, bounty hunters are the one who has the big effect on the price of the newly created altcoin in the market.
Agree. Which is why most bounty managers pay in the project's own token instead of ETH. By paying in that specific token, the project could grow in demand and popularity. Bounty hunters would mostly hold that token to sell at a later point when prices go up. However, if they receive payment in ETH, then the project would be doomed as it cannot bring a useful product to its users (in this case a unique token). The token drives the value of the project and by sending payments in such token, it will promote its usage within the market.
Still, there could exist a bounty campaign where users would get paid in ETH if the bounty manager decides to do so. Since ETH is more liquid than most tokens available in the market today, it makes a great asset for trading and profiting over the long term.
Nevertheless, anything could happen in crypto land. Therefore, it's possible that bounty hunters could get paid in ETH sometime in the future. Just my opinion
