they give 5000 USDT as a rewards to those who will found bugs in the website + 50000 tokens . I don't see any one join in that campaign but its good to try since the rewards they give is not bad to try.
Yeah they are rare but they do exist and to be honest it is not something that the errand-boy type spamming campaign like the ones for twitter and facebook. Bug hunting is a professional job and so if they are paying something for it, it is usually a big amount as you have pointed out. Hence not everyone is qualified or knowledgeable to take part in that.
Moreover if some is a security expert they would have a better paying job itself than go for a bug bounty but there are freelancers and younger students who might be interested in them.
