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.
Of course you are right, for hunters it is very cool, but for the ICO company it is not profitable. Because they hope for speculation, with their coin, without reference to the Ethereum, when they come to the exchange. Almost 85% of the coins when entering the memory exchange raise and lower the price. It's intentional.
