In crypto trading jargon, DYEC is short for do you even chart.
DYEC is a variation on the famous DYEL exclamation from online fitness communities (Do You Even Lift?) which is posted when someone gives bad advice or talks down to others while making it obvious they don’t know what they’re talking about.
By calling out bad TA you either get something to brag about on the internet (more common on Reddit), or you’ll get totally hammered by super loyal fanboi ultras (more common on Twitter).
An indepth look at DYEC is here.
