What is IYKYK
IYKYK is an acronym that stands for "If you know, you know."
This may sound like a meaningless phrase, but in the crypto community, some topics, projects, technologies, or events have complex background information that only those who understand it can grasp the logic behind it. When these topics are mentioned, people use IYKYK to indicate that only those who know the background information can truly understand its meaning.
IYKYK was first introduced into the Urban Dictionary in April 2016 and has since become a widely used term in the crypto community, often used to draw attention to certain posts. You can frequently find posts tagged with #IYKYK on Twitter, especially when new projects are launched.
In short, you can simply understand IYKYK as a subtle form of self-promotion because only those who know this particular knowledge or experience can truly understand it.
