🧠 The “Missing” 1 BTC Puzzle: A Crypto Classic That Still Baffles Many!
Three friends walk into a restaurant and split a bill of 30 BTC — simple, right?
Each one pays 10 BTC, making the total payment 30 BTC.
But here’s the twist...
💡 The waiter realizes the bill was actually 25 BTC, not 30!
To fix the overcharge, he brings back 5 BTC in 1-BTC coins.
Now, he can't split 5 BTC evenly among three people — so he gives 1 BTC back to each friend (totaling 3 BTC) and quietly keeps 2 BTC as a tip for himself.
Let’s Break It Down:
Each friend paid 10 BTC
Each got 1 BTC back
So each actually paid 9 BTC
✅ 3 friends × 9 BTC = 27 BTC
Out of this 27 BTC:
25 BTC went to the restaurant (actual bill)
2 BTC went into the waiter’s pocket (tip)
🔍 But wait... 27 + 2 = 29 BTC?
Where did the last 1 BTC go from the original 30?
🧨 Here’s the Catch:
This is a logic trap, not a math error.
You're not supposed to add the waiter's 2 BTC to the 27 BTC — because that 27 already includes the 2 BTC tip!
The correct breakdown is:
✅ 25 BTC (bill) + 2 BTC (tip) = 27 BTC
✅ 30 BTC - 27 BTC = 3 BTC (returned to the friends)
So nothing's missing. The math checks out.
It’s just a clever way to misdirect your brain — and it works every time!
🤓 Moral of the Story (Especially in Crypto):
Always double-check your change…
Whether it’s cash, crypto, or a late-night food bill in BTC!
The blockchain doesn’t lie — but sometimes, logic tricks do. 😉
