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

Lately it just seems completely pointless.

On the other hand, signature campaigns (bitcoin paying) have been doing quite well in the forum. I am talking about Bitcoin projects like crypto casinos, Bitcoin Mixers, Exchanges etc. as they attract quality and high rankling users and not spammers and account farmers. If your target is outside the forum, you will have more creative to reach your audience.
