It's possible for an investor to avoid scam projects but almost impossible for a bounty hunter not to promote scam projects directly or indirectly. Some projects that have been tagged scam suddenly do well. Ixium (XXA) that was tagged a scam has been listed and planning on their road map
So the big question should be how can we actually differenciate between a scam and a legit project?
This is one of the many reasons some bounty hunters only settle for automated bounty sites but it didn't pacify the issue of payment still. I really do hope that a lasting solution to this comes forth soonest.
I also believe TWT will do well in future because their wallet itself has attracted many users due to its user friendly interface and less fee for transactions. Long before TWT came into the picture, I have always been a fanatic of trust wallet because I barely experience failed transaction when using it.
