As there are multiple ways to get your crypto project to the public, but what are the recommended ways now adays?
In the forum, you can advertise in bounty or signature campaigns, where you can pay either with Bitcoin or with your campaign codes (almost for free), or a mixed payment between Bitcoin and your campaign codes, which is the cheapest and most secure method.
You can try to advertise on X and Reddit, and I see some ads on YouTube, but I do not know that. You can also pay influencers to advertise for you on those sites.
