Once there lived a little Ninja who spent his days doing what ninjas were supposed to do. One sunny, beautiful day, the Ninja was walking along the seashore, counting his breaths and steps. He was practicing dynamic non-doing, as he did almost 99% of the time.

While walking, he suddenly noticed an Old Whale sitting on the sand, staring at a laptop. The Whale's eyes were bloodshot, and his face looked pale. Driven by curiosity, the Ninja approached.

"Hey, you fat fish, what's up? What are you doing?"

The Whale glared at him. "I am trading Bitcoin. Who are you, you little nasty creature?! And I am not fat! I am a Whale!"

"But fat is something before and after the Whale, fish!"

"Don’t call me a fish! I’m a mammal. And why are you so rude?"

"I am a Ninja. I am neither rude nor polite. Neither good nor bad. I am simply what is here, my lovely Mammal Fish."

The Whale snorted. "I see, just another crazy bumpkin. Go your way; I have trades to make."

"Alright, alright, Mister Mammal Fish. But tell me before I leave—what do you trade Bitcoin for? XMR, Litecoin, Doge?"

"Hah, easy. I trade it for money, you little rude creature."

"You mean for USD?"

"Yes," answered the Whale curtly.

The Ninja smirked. "That’s very foolish of you, Fat Fish. You’re definitely not a mammal. Every mammal knows that money is just colourful paper. Trading something precious for paper? Ridiculous, dear Mammal Fish!"

Something shifted deep within the Old Whale. Somehow, this little rude Ninja had touched the innermost layers of his soul and mind. From that day on, the Whale never again sold Bitcoin for USD or any other beautifully coloured papers.
