Bitcoin doesn't work by passing tokens around to represent the value. In a Bitcoin spend the value is simply added to the wallet/address's balance. Any further spend is deducted from the wallets balance.

The "coin" is not a single token that lives on and is broken apart to be spent, so there's no way a coin could self destruct after being transferred.

You keep telling yourself that.

I understand fractional coins. I was over simplifying for brevity. I'll give you a hint. You have to move the coins between two wallets you own before you create a coin that will "break" when it goes in to the third's wallet. The Third wallet accepts a coin that no one will take afterwards. The coin becomes undependable.

unspendable. Damn you Autocorrect.
