Many of ICOs allocate some of the tokens to participants in bounty campaigns. Don't you think it is better to give bounty participnats reward in ETH?
1-2% of the money raised is not so much and bounty participants deserve that. Also, it can cause more investors to attract. Because they are no longer worry about the price fall after bounties are paid.
It will cost less for the teams running the ICO to award bounties with tokens and just allocate part of the tokens for bounties. As a bounty hunter, I would really prefer Eth as payment as it's easily tradeable.
