### Scenario: Merchant Accepts BTC
- Customer wants: to pay with Bitcoin
- Merchant wants:
    - To receive dollars
    - Simple deployment
    - Low risk
        - Tech risk
        - Security risk
        - Exchange rate risk

### End Result
- Customer: pays Bitcoins
- Merchant: gets dollars, minus a small percentage
- Payment Service: 
    - Gets Bitcoins
    - Pays dollars (keeps small percentage)
    - Absorbs risk: security, exchange rate
    - Needs to exchange Bitcoins for dollars, in volume

:::warning
The user is exposed to exchange rate risk to some degree since they must hold bitcoins at least temporarily to be able to pay with bitcoins.
