|   Someone asked what it's good for, Satoshi said you could
| use it to do spam filtering.  I said, no you can't

| About a decade later I bought some bitcoins from a vending machine and
| then paid for a coffee at a shop near the Vancouver IETF just to see
| if I could.

This demonstrates how bitcoin is used for buying drugs, not stamps.  
Vancouver is famous for even stronger drugs.
