In social media your followers can be non-crypto fan so it's not like always a good go with social media marketing, that's why always the Signature campaign is always more than social media campaign.
Yes, you are right
because everyone in this forum is people who are interested in crypto while not all of them on social media are crypto fans, so the signature campaign is considered better and more effective for advertising the project, therefore the results for the signature campaign are bigger ,rules about social media are also easier because we only repost or retweet while in the signature campaign we have to make constructive and quality posts
