scammers have taken over crypto space and they are building unrealistic projects to fool investors,
I wont say to that extreme but yes you have to consider every new project to be a borderline scam and thus shove it away when presented in front of you. Some investors who get fooled are not worthy to be called investors anymore if they are still putting money in non-legal securities like ICO coins. They should know better how to take care of their money and these are only wannabes get-rich-quick people.
with the help of bounty hunters they get things done easily and in the end they either don't pay at all or ruin their promises and split the reward,
Better to focus your time on learning something skillful than wasting time on bounties. Bitcoin paying campaign are also going on, which is a good thing to join though.
no law is holding them back, they have nothing to be scared of, project teams can do any how they feel like
Sadly it is true. Once you give them your money, it is gone. Whatever coin they sell to you, it is worthless anyway.
