When it comes to marketing, you guys cannot fail by advertising a game in which players can make profits, you just need to pay 2-3k montly to a good marketing proffesional to make it happen!
This is not gonna happen. Marketing guy would demand much more than 3K. He would ask for 30K if not more. Building up hype for unproven coins is not easy and is as costly as development services, but if u dont wanna pay that much u can find a nurse on indeed.com or another recruitment site, who would do advertising for under 3 bux per week.
