Many people come here to post in order to earn the money. But there are others who are running their business through this site. If you own a gambling casino or any other business related to crypto, you can promote it on this forum and can get nice traffic.
Also if you have any skills, you can advertise your service and get some work and develop your portfolio. There are many ways where you can earn much more money other than just from the signature campaigns.
Actually there is money in this forum but not that quite enough for a living. As a bounty hunter earning few cents for promoting signature is alright as only for small expenses in which it will not take much time to promote a project. 5 Posts per day is already enough to earn few cents for prepaid load or buying snacks if join in a good paying bounty project. However, mostly of the rewards here are not really that high and this is why we should consider this as part of having fun to be here while learning about cryptocurrency. Some sort of motivation and well have to also to do what is intended for us to keep the project doing well.
