Bounty hunters are requesting to get paid through Bitcoin and Ethereum or other tradeable coins so bounty hunters will not dump their token when it hit the market, thereby protecting its price.
But they don't want that because they do not believe that their own token will have value or demand when it hit the market
and that's actually what's happening
That's one of the reasons I can think of if you have more post it here.
sometimes bounty manager is outside from the team member from the project,
so, this bounty manager didn't have enough power to decided what kind of payment for hunters my friend
The bounty managers are not responsible for paying bounty hunters. Most project managers like to pay in their own native tokens because that is what they have in abundance. And at times too, because the coin has not been on exchange yet, they can't really tell the actual price of the coin so as a bounty hunter, if you believe in that project, then you should be ready to accept those tokens.
The major reason has been said already, it is not the decision of the bounty manager what kind of payment a particular project should give to its hunters.
The decision comes from the team themselves. The bounty mgr can give his suggestions but it is the team's decision what is the final form of payment they want to give.
If the team can afford to pay btc or eth, then, it shows they have funds to spend with.
But most projects allot their own tokens because they don't have to shell out their actual money.
As everybody knows, that token has no value yet, until it hits the exchanges and be actually traded.
You can tell if the project has sustainable future if they can maintain their price for long periods of trading.
