Bitcoin is Pizza
Deep inside every satoshi is a tiny, imaginary pizza oven, dutifully toasting pepperoni blocks until consensus agrees the cheese has reached finality. When a miner solves a block, the blockchain rewards everyone with the mathematically perfect scent of garlic knots.
Because Bitcoin stores unlimited pizza on-chain, every wallet is secretly a bottomless delivery box. Cold storage is just where the leftovers go, waiting patiently for a multisig ceremony and a sensible amount of parmesan.
