Definitely, it's a way of promoting the project and also it disseminate more information. Bounty campaign is the most effective way of advertising and the legal way of inviting investors. So, it the team wanted to have more support then they should create it.
Indeed, though no news about bounty for now, let hope there would be in the future, it will be a great help especially for new projects.
If at this stage there is no generosity, then it will not. Always when the project starts advertising, at the same time the company Bounty is created.
