Sorry for your loss if you promote a trading bounty project and still get worse results from them, it happens, get used to it and mind you not all listed bounties cheat bounty hunters,
It's true not all bounties are scam but we must always be careful. Because there are many projects that take investors' money and do not develop their projects. So the projects die. Not all projects in the market are good prices.
Scammers are inventing new ways to scam people, they evolve as the market evolves. We learn about their tricks, so they need to come up with something new. I participate in bounties and I try to research a project in the best way I can, and I am aware that I can miss something and to get scammed again, it happens to me and I think it will happen again.
