Not so profitable I say. You need to look at the project first and think if they're going to be successful with their launching and crowd sale. Results do vary and the bounty won't be successful if the sale isn't successful as well. Think of it on where the value of the tokens that are going to be shared for that bounty. It's going to come from the crowd sale and the value will be determined by its market. So, it's really going to rely on it.
