I believe that investors of Polkadot ICO where the very lucky investors since the ICO was launched few years ago. How i wish that there's a bounty for this project but i found nothing except for their bug bounty that is far beyond my skills. With a project such this that is well funded and with so much hype, i can only hope less for them to offer bounties like i used to participate in this platform.
Bug bounty is the only available bounty for PolkaDot, but i actually see you are promoting PolkaDot in your signature. I searched about PolkaDot signature campaign but found nothing. Did you create this signature by yourself and start promoting without waiting for a reward?
Well maybe the reason why polkadot didnt conduct bounty campaign before is because they are confident that the project will still become successful even without the help of bounty hunters that will promote thier product.
To be clear here, almost all succesful projects which has been started with an ICO for fundrise didn't run a bounty campaign to promote themselves in social media. Ethereum is a great example among many other projects.
