Although I would advise been a full time Crypto trader is better than doing a mass bounty hunter because there are lot of scam ICO's where at the end you wouldn't get paid even if been paid the coin might not enter market but If you have a lot of cash I mean capital I would suggest you be a cryptoinvester and trader it's really a huge benefit rather than been a bounty hunter. No need of ranks for signature or any other campaign it's you and your smartness in trading in Market.
