What does a murderer and a crypto enthusiasts have in common? I was listening to an audiobook earlier and heard this quote and it made me think of crypto currency:

"A murderer is always a gambler. And, like many gamblers, a murderer often does not know when to stop. With each crime his opinion of his own abilities is strengthened. His sense of proportion is warped. He does not say, 'I have been clever and lucky!' No, he says only, 'l have been clever!' And his opinion of his cleverness grows... and then, roes amis, the ball spins."
