📦 What is Bitcoin?

Bitcoin is like digital gold, but lighter—no need to carry bars around. You can send money worldwide just by using your phone, and the transaction fees are more than half cheaper than bank transfers. Its “ledger” is stored on computers all over the world, and no one can change it—just like a notice on a community bulletin board. Once posted, everyone can see it. Trying to secretly alter it? No way!

🚜 Mining = “Digital Construction Site Bricklaying”?
Miners use computers to “mine” Bitcoin, similar to workers on a construction site exchanging bricks for wages. The better the machine and the longer it works, the more Bitcoin they can mine. But these “bricks” are special: every 4 years, the mining reward halves. The cost to mine one Bitcoin now is enough to buy a high-end gaming laptop five times over. Someone used 10,000 Bitcoins to buy two pizzas back in 2010, and now those two pizzas are worth 800 million dollars—arguably “the most expensive takeout in history”!

🎢 How to ride the roller coaster of prices?
Bitcoin’s price is like a theme park roller coaster. In April 2025, it dropped from $80,000 to $78,000, then quickly surged back up to $103,000. Some say it’s “real estate of the internet age,” bought and held for appreciation; others see it as “cryptocurrency lottery tickets,” soaring to the sky and crashing down, making investors heartbroken.

Bitcoin vs. Everyday Items | Features | Metaphor
Total supply fixed | 21 million coins, limited supply | Rare stamps, limited-edition sneakers
Decentralized | No boss controlling, maintained by global users | Shared community parcel lockers
Price volatility | Daily fluctuations over 10% | Bungee cords, the “big pendulum” of the stock market

Some people see Bitcoin as a “digital passbook,” while others think it’s just a “useless string of code.” But no matter what, it’s like the internet 20 years ago—no need to understand everything. Just remember: don’t gamble with your grocery money. Use your pocket money to “buy a ticket” and enjoy the show!

Would you like me to rewrite this with metaphors like “milk tea” or “game skins” to make it more relatable?
