sale caro el restaurante , dime que restaurante es ese para no ir...

Three friends walk into a restaurant and split a bill of 30 BTC — simple, right? Each pays 10 BTC. But then the waiter realizes the bill was actually just 25 BTC, not 30!

He brings back 5 BTC in 1-BTC coins. Unable to split it evenly, he gives 1 BTC back to each friend (3 BTC total) and quietly keeps 2 BTC for himself.

Now let’s break it down:

Each person effectively paid 9 BTC (10 paid - 1 returned)

Total paid = 3 × 9 = 27 BTC

The waiter kept 2 BTC

So... 27 + 2 = 29 BTC? But wait... they originally paid 30 BTC 😱
Where’s the missing 1 BTC??

👉 Spoiler: It’s a trick of logic — the 2 BTC kept by the waiter is already part of the 27 BTC, not something to add to it.
25 BTC (actual bill) + 2 BTC (waiter’s tip) = 27 BTC
The 3 BTC returned completes the original 30 BTC.

It’s not missing — it’s just hiding in the math 😉
A classic brain teaser with a Bitcoin twist — and a reminder: always check your change, even in crypto! 🧠💰
