How do you use DEXE black hair?

Excuse me, I've heard some people discussing the use of "DEXE black hair" in the context of cryptocurrency and finance, but I'm quite confused. Could you elaborate on what this phrase actually means? Is it a reference to a specific strategy, tool, or perhaps a metaphorical term? If it's a strategy, how does one effectively utilize it in the crypto market? Are there any specific steps or considerations one should take? Additionally, is there a risk associated with employing such a technique? Your clarification would be greatly appreciated.
