After doing research on the projects the rest is still on luck, not all good bounty projects do well after, there are high quality bounty projects in this forum that haven't launch till date or so something at all, some even don't give out updates anymore and members of this forum are already calling them scam
It's true we didn't know the project was a scam or not before it was used by many people and very useful. always believe in personal analysis to determine the choice of projects that will succeed
