It would be great to participate in such projects where the payment is at least 50/50. Perhaps now there is such projects, share please if will find! ETH is a more stable currency than new coins, but the project that we advertise is probably good and you want to get its tokens!
Now, there are practically no worthy bounty campaigns, especially with payout in ETH. Decent projects are increasingly abandoning the typical bounty campaigns, as they often have a bad effect on reputation. The last project that made 100% payment in ETH - it was DAOstack.
