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.
If you do not intend to take that investment, then you should move to usd to many pictures of the market for their money. good luck !!!
