Man I hope you don't mind me saying but you got a real tough job ahead of you, getting people to sign up and actually use your site is not going to be easy. Whatever you do don't hire posters to populate the forum and make it look active, that stuff never really works. You need people that genuinely interested and for that you'll have to come up with ways to make the site stick out from the hundreds of other crypto forums around. It's hard but not impossible. Good luck man.
thank you, i'm aware of that. It will be really tough task to get active members. I'll start with advertising soon and will think about some kind of promotion for members.
