And you really follow this strategy? You know everything about the project? So why then you participate only in a bounty campaign and you don´t apply for an Ambassador position for example? 
I personally have been onboarded on a couple of teams that I originally just participated in their bounty campaigns for. This is how I became a Sheriff for Bounty0x, then quickly rose all the way up to Distribution Manager. I've also became a Community Manager for a couple of projects such as ArtPro after participating in their bounty campaign.
If you follow these tips I posted below, the teams you invest your time in to create quality work will take notice to you pretty quickly. They are always looking for dedicated community members to help increase their marketing or community engagement, and if you are looking for even more tokens, I advise you get busy as there are so many awesome opportunities out there.
