I know this have been discussed several times on this forum but yet I will like to drop this again, I'm sure few new developers are among us here, so here we go
It will be a whole new story if new projects can start paying bounty hunters in USD or stablecoin, this have few advantages over paying with your own tokens, if new projects find it as a most for people to try out their new Blockchain they should use airdrops instead, airdrops has the lowest rewards, hardly to get 2$ in airdrops today
As for bounties please start paying in USDT, DAI or USDC, this will erase your sense of 'bounty hunters are killing new projects' idea
If I'm not mistaken, there is a bounty project that pays with stable coins or coins that are well known, but the requirements are quite strict and you could say the pay is not that big. However, it is guaranteed to be paid.
If we get paid with the project coins / tokens, we can get big profits as long as the project is successful. But in reality it is very few successful projects.
