It seems that some scam projects manages to get on exchanges and pretend like everything is normal, they have good aim of exiting scam by introducing bounty campaign that will take weeks and along the way while bounty hunters are promoting the projects some investors attention will be caught, after bounty is about to end the coin or token value will now dumped, by the team
This is common already for most of the new projects.
This is the sequence or the cycle.-A new project is born and will be advertised here.
-They will launch a bounty campaign where bounty hunters will be paid as they advertise the project thru different ways.
-After the campaign, there are some options that most of the teams are doing. They will distribute the tokens but will be locked until such time it is tradable already. They will make some spoils and will distribute the rewards of the bounty hunters after some months. This is the worst scenario. Some of the projects don't want to pay the bounty hunters until they list it on an exchange and then after that they will dump it.
As a bounty Hunter, we create awareness for them to attract investors and they will dump on us leaving bounty hunters with nothing, it seem this is the new trick now, Spyce and Blockburn and IMO did this, no more volume, there was dumps and bounty hunters received nothing
If you are saying that this is a new trick then definitely you are new to the world of bounty hunting.
This kind of "trick" you are saying is already here for a long time. Many projects in the past are doing this kind of thing. Listing the token into an exchange were the developers and the investors will dump the coin and will be a dead coin after few weeks.
This is the reason why I stopped bounty hunting already. Most of the rewards that I get either doesn't have a price (not listed on an exchange) or it is listed on an exchange but your trade will not be liquidated because there aren't have volume in it so it is still useless.
