In both ways you are the loser . Why ?
The scam ico get free advertising without paying you a damm penny while you could have advertising his scam ico for +2 months. Ouch it hurt right ?
And in another side you risk your account in BTT to get painted red and you may not be able to join compaigns in the future .
So to avoid that try to make a deep search about the project you are joining also about the bounty manager .. since good managers accept only good projects ( you cant be sure 100 % but at least you did your part and reduced the chance of getting scammed
)
