the project you promote 2years back can still come up and give you awesome reward, delays takes place sometimes that makes project team keep postponing listing on exchanges, imagine promoting a project in 2018 paid you big reward in 2020 after you've already zero your mind that it's over? I want bounty hunters in the house to verify this, true or false??
Anyways, do not underestimate projects you promote a year or two years ago, they can still pay up and secondly do not leave or exit their telegram channel no matter how many years it's been, if you do you might be denied of your rewards
Joined a campaign last 2018, I waited for it to have value since I have no choice because of the sluggish response of the team to apply on an exchange, it's not quite rewarding but I really hold on to that token and bought some in the Etherdelta "Unofficial exchange" was one of the top coin holder of this certain coin, still waiting for it to gain its momentum.
