As a rule - no. A project that did not collect the minimum required level of funding does not distribute tokens to members of the bounty. And also returns all the funds to all investors. (This is for the case of an honest project, not a fraudulent one)
The fraudulent ones too will not even distribute any token since there is no project involved, it is even logical to know that a project that failed to meet up and mandated to return people’s investment will surely not distribute token because the project they raised fund for has automatically been closed till they feel deemed to reopen it .
We also need to study the projects we are promoting to also see if it can stand the market so that we don’t end up losing our time we would have committed in valuable things.
