It depends on the kind of marketing team you hire and also your target audience. Back in the day, Bounty campaigns used to a thing with both the projects and bounty campaigners mutual benefiting and then came the cheats, bots and spammers
Yeah. Back around 2017 and 2020 when I attempted to join one bounty, it was just like a hit and miss kind of stuff. You never know if your 3-month work would be worth it in the end. When ICO became like a hot topic, it was just like being visited slowly by scammers until nobody even dared to do ICO bounties anymore.
Not sure if airdrops is like considered to be "bounty campaign" since back then, they were like separate stuff but to this day, I heard that there were still some airdrops worth doing, but the risk is just getting shitcoin into your wallet.
For marketing on Bitcointalk, of course, signature campaign is the answer, I don't see bounties still being effective here. There are much better platforms out there that you can use for bounty programs, for example like
Galxe or
Zealy (previously Crew3).
That is an option if you are only going to make 1 program out of the 2 mainstream programs on the forum, but it would be better if you implement both programs on the forum and also continue to use the mainstream platforms out there too.
Although to be fair, the way that bounties work back then were still effective, not sure if they still do Twitter, Facebook, Reddit bounties, but with that campaign, you have plenty of audience that could open their ears and eyes for your project depending if your project is worth visiting.
