Oh yeah, sure! Bounty hunters contribute a greater part to the growth and development of many coins. In fact, when you examine the contracts of many ETH-based tokens, you'll find that the number of token holders only increase after bounty payments, and that's a major contributor to decentralization. Moreover, there are bounty hunters who're also traders and investors and as such the better they see a coin to be, the more they invest or trade into it helping build/develop that particular coin.
