Takuto Kimura sat cross-legged on his nap mat, surrounded by an army of building blocks. The rain outside was relentless, the rhythmic pattering against the window serving as a perfect soundtrack to the drama of his budding business empire. The kind of drama that could be written in gold—if only his crayons weren't currently scattered across the floor, half-chewed by his younger sister.
He was in the midst of his masterpiece: a new economic order, poised to revolutionize the sandbox world. Forget the mundane, the ordinary. No, Takuto's vision went beyond simple playtime economics. He was establishing something more. A new currency system.
"The fiat currency system has collapsed," he wrote seriously on the back of a piece of diaper packaging, as if that made it sound more profound. "We must establish a new currency order."
His eyes glinted with pride as he gazed upon the fruit of his genius: the "Building Block Coin" system. It was as perfect as any three-year-old's plan could be.
The rules were simple but sophisticated.
Base currency: Red blocks. One red block = one minute of toy usage. Easy. Transparent. Democratic.
Credit currency: Blue blocks. Tied to the "Kimura Corporation" goodwill, these little guys could be used for overdrafts. No one was going to stop him from offering loans to all his sandbox peers.
Futures product: Yellow blocks. Ah, the most interesting of all. Promises to pay double tomorrow, but Takuto knew full well that tomorrow would never come. Classic pyramid scheme? Perhaps. Genius? Definitely.
"Perfect," Takuto whispered to himself, admiring his creation as though it were the blueprint for a new world order. "Next, all I need is—"
Slap!
A soggy green block smacked him square on the forehead, snapping him from his reverie. He looked up in confusion, wiping the drool from his face, and there stood Kenta, grinning like the carefree agent of chaos he was.
"What kind of coin is this?" Kenta asked, his voice dripping with mockery, holding a green block between two sticky fingers.
Takuto didn't even flinch. "Toxic asset," he replied dryly, wiping his face off with a napkin, not bothering to elaborate. He had bigger fish to fry than dealing with Kenta's moist contributions to global economics.
The first week of the Building Block Coin system, however, turned out to be a monumental success—well, if you could call it that. A little too monumental for its own good, maybe.
The Secondary Market Boom
The sandbox was buzzing with excitement as a "stock exchange" was set up under the slide. It was chaotic and disorganized, but everyone involved felt they were a part of something greater than themselves. Even Kenta, still drooling, somehow managed to get involved in trading blocks for biscuits.
The exchange rate fluctuated wildly in real-time:
Morning: 1 red block = 2 biscuits
After nap: 1 red block = 1 fart (because Kenta let out a particularly loud one that echoed through the sandbox, reverberating through the very soul of the financial system).
The market was volatile, but no one cared because they were all too busy watching Kenta fart like a financial wizard.
Financial Derivative Innovation
As the market matured, it didn't just stagnate—it evolved. Enter Ai-chan, who, never one to miss an opportunity for a good deal, introduced the "Bowtie Option." Her pitch was simple, yet baffling:
"Give me 3 blocks now," she said in her most persuasive voice, "and I'll braid your hair beautifully tomorrow~"
Of course, tomorrow came, and instead of the stylish braids everyone had expected, Ai-chan gave all the boys in the class sky-high pigtails. Some of the boys loved it, while others—like Taro—spent the rest of the day hiding behind the toy boxes, pretending they were in a very intense game of hide-and-seek.
But hey, it was technically a return on investment. Everyone knew that hair was, after all, the most volatile of assets.
Leverage Trading
Things took a dramatic turn when Ryutaro, not one to let anyone outdo him, borrowed a substantial sum of 100 blocks to short the sandbox. Ryutaro had grand plans to crash the market and buy everything back at a fraction of the price.
Takuto and the other kids in the sandbox, acting as retail investors, managed to hold on to their assets, causing Ryutaro to lose everything.
In a truly desperate move, Ryutaro tried to cover his debts by offering a truly strange form of collateral: his dinosaur underwear.
Takuto couldn't help but chuckle. What was next, a mortgage on his lunch?
The Crash: A Great Financial Collapse
But as with all great bubbles, it was only a matter of time before the system began to show cracks. On Wednesday, during snack time, Kenta—forever the wild card—introduced a new kind of block to the market: "highly counterfeit Block Coins," made with an assortment of snot, dirt, and some leftover raisins.
Aichan was the first to discover the truth, screaming when she found out that the "coins" were sticky and just a little bit too moist to be legitimate. A panic sell-off began immediately.
"Kimura Corporation is going bankrupt!" Ryutaro shouted, spreading the rumor like wildfire.
Before anyone could stop him, a full-blown run on the market erupted. Every kid in the sandbox suddenly demanded biscuits in exchange for their red blocks, convinced that the whole system was crashing down around them.
"Everyone, don't panic!" Takuto shouted, standing on top of the toy box, trying his best to sound like a wise and seasoned CEO. "This is just a technical adjustment!"
Of course, just as he said those words, the box he was standing on cracked open, and over two hundred blocks spilled out, creating a colorful mess that looked more like a stock market crash than anything resembling stability.
The Ultimate Contingency Plan
Desperate times called for desperate measures. Takuto quickly sprang into action, activating his ultimate contingency plan:
Mortgage his spare diaper as "last liquidity."
Promise "double biscuits tomorrow" (which, he knew, was physically impossible).
Secretly change the clock in the playroom to make "tomorrow" come early.
It was a last-ditch effort, but it was all he had.
Unfortunately for Takuto, his plan didn't go unnoticed for long. The scam was exposed when Ryutaro, ever the opportunist, led a group of kids to the doghouse to corner the capitalist.
"Catch that capitalist!" Ryutaro shouted triumphantly.
Takuto tried to wriggle deeper into the doghole, but he got stuck halfway, his little legs sticking out in a rather undignified manner.
"You're trapped, Takuto!" Ryutaro yelled, pulling out a marker and drawing a large "BANKRUPT" sign on Takuto's exposed butt, complete with the date.
At that moment, Mrs. Nakajima arrived to pick up her child and paused, her eyes wide with surprise.
"Oh my," she said, looking at Takuto's backside. "Do kids these days doodle so professionally?"
Takuto was so embarrassed he could've died. "That's a balance sheet..." he muttered under his breath, though no one was buying it.
That night, after the dust had settled and Takuto was safely back in his room, he reflected on his many lessons learned. He grabbed his doodle book and began writing with a solemn face:
Never use snot as an adhesive (financial infrastructure is important).
Never let Kenta participate in any activities that require credit.
Always leave an escape route wider than your own butt.
And finally, in the center of the page, he drew a big, crying face with the words: "Turns out, whether you're three or thirty—when the bubble bursts, the one crying the loudest is always the CEO."
And with that, Takuto closed his doodle book, pondering what his next business venture would be. Maybe a lemonade stand. Or maybe something much bigger. But for now, he was just glad to have survived the first blockchain crisis.
