When explaining bitcoins advantages over cash to someone else, there are a few things that come to mind:
1. They cannot be counterfeited
2. Can be sent anywhere in the world with no (or very very low) fees
3. Mining fees dont go to big banks
4. Low transaction fees, coinbase estimated bitcoin could reduce payment processing fees worldwide from $500 billion to $50 billion, so 1/10th of current level
Any other to add to the list?
5. The value of bitcoin will increase(deflate) over time as opposite to cash(inflate).
6. The value of Bitcoin is volatile and although you may go to the store with $100, by the time you get there you might only have $80
