each project has a bounty program, and I think this is a good way to promote an ICO. build a large community and give gifts to campaign participants. social media has always been part of the campaign, and you have to work hard to convince the team to replace the campaign program on social media.
great work.
just post information about the project in different groups and the build community are different things. To reach the target audience, you need a strategy and a big team. I do not know how one person can do it. Unless using other services to implement the strategy. for example,
upvotes.io for reddit, chat bots for telegram, some
servicies for posting on twitter.
