Kandor Invented Bitcoin!!

Nightwing and Flamebird are investigating the seemingly impossible locked-room murder of Kor-Am, the man in charge of Kandor's central computer system!!

Investigation reveals that Kor-Am was apparently living well beyond his means...

Well, see, it turns out that Kandorian currency is entirely on the internet (or whatever they called it in 1978 Kandor):

Ahh, Tonzols!!

Well, more investigation reveals Bitcoin Tonzol shenanigans have been going on!

Well, it turns out that Kor-Am was pulling the old "steal the rounding errors off of every transaction and no one will notice" trope.

And it turns out that Gav-Et got greedy, and killed Kor-Am with a thought-transfer helmet, planting a "hypnotic" suggestion in Kor-Am's mind to die when he hears a trigger phrase.

Kandor--hotbed of financial crime and crazy-ass murders!!
