You have to see the founder and team of the Bounty, sometimes many of them are fake, just want to deceive investors, overall you have to check the web and their white paper well, many things to learn in the assessment of the Bounty.
I realize a few bounties are currently successful and honest, the rest are problematic of all.
Beside make our research to know with good project on team developing this important thing why choose experience with Bounty Manager because they know about fake team developer, try to get investor and coins success sold on public sale then not listing yet on exchange market or listing with dapp exchange market only like Pancakeswap for usually BSC coin network right now.
Most difficult nowadays to find with potential project bounty campaign after with many time price drop when listing and reward sending to bounty participants, not only with reward reduced but also investor get loss money with bad project building because have lower price when listing on exchange market.
