Thank you for your appreciation. You are correct I really need a big budget to achieve a good result. I'm thinking of giving rewards worth of bitcoin weekly so that many users would join the platform. Also, I'm thinking of giving rewards to those who would invite to come to the community(like an afffiliate).
Be careful with this strategy. I've known several forum which starts their advertisement by giving away/running a campaign dead after the campaign is over. I'm pretty sure organic traffic will come to your site when someone can find something unique which is not replaceable or can't be found on another site.
Anyway, good luck with your project.
