DYOR stands for do your own research. It is a common phrase used by cryptocurrency enthusiasts throughout the internet due to how fast and easily misinformation can spread.
DYOR aims to reduce the number of uninformed investors in cryptocurrency. It encourages them to research and understand a cryptocurrency before investing so that they can answer precisely why they are buying that currency and supporting that project.
The term is also often used as a disclaimer when cryptocurrency traders and enthusiasts make public posts or share their market analyses on social media platforms.
