Now many people disappointed in bounty campaigns and in tokens and do not participate in them.
They do it right, there is nothing to help scammers.
But how to understand what project is scamm and what project is not scam? Very often it is realy difficult to do.
Well, first of all, you need to study all the project documentation, see who is in the team, whether they had successful projects before. But of course it is difficult for a beginner to do this.
I agree that it is necessary to have experience to choose a good project for investment. Newbies very often invest money in scams.
