No such thing as old bounty, the project you promote 2years back can still come up and give you awesome reward, 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 old projects you promote, 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
