Are new projects supposed to be well successful today to pay bounty hunters their promised payment? If they raise huge amount of money paying bounty hunters won't be a big problem, am I right ?
The question is - would they able to get sufficient funding or investment?
The question is - would they able to pay even if they had succeeded and wont scam out those bounty hunters?
Everything would be still questionable because there is no such guarantee that those arent scammers since from the beginning.
A bounty hunter has his own responsibility to assess those things at the very beginning.
No one can help you in evaluating the project but yourself. You can check some hints from their thread and social media channels.
As you can't determine if they will exit scam or not at early stages, you can only rely from what they are disclosing to the public.
But once you got the notion that they will turn as a scam, better stay away as early as you can.
Don't let them waste your effort long time. Help yourself as no one will.
