Where to get flux in Fallout 76?

Hello there, fellow Wasteland explorer! I'm curious, for those of us delving into the depths of Fallout 76, where does one procure that elusive currency known as Flux? I've been hearing whispers of its usefulness in crafting and upgrading gear, but I've yet to stumble upon a consistent source. Is it hidden in the ruins of long-forgotten settlements? Could it be garnered from the spoils of victorious battles with the local fauna? Or perhaps, there's a secret trader in the wastes who holds the key to its acquisition? I'd appreciate any insights you might have on this elusive but potentially valuable commodity. Let's hope our combined efforts can shed some light on this mystery!
