Mention velocity measures how fast social mentions are accelerating, not just how high they are.
Acceleration can lead price and market-cap rank moves when a narrative is just catching on.
In research workflows, Mention velocity is usually interpreted with Social volume, Attention acceleration, Hype momentum, and Hype score rather than as a standalone signal. Acceleration often matters more than absolute mention counts. Loud but fading hype is a different setup from quiet but rising chatter.
