Minor changes to the stories, updating to reflect current common uses and current price
=== 2. How Bitcoin Works
* Buying a [line-through]#Cup of Coffee# Laptop
Updated Alice and Bob's story. Buying a cup of coffee is no longer sensible "on-chain", due to the value of Bitcoin and on-chain fees. Instead, small retail purchases are now a use-case for the Lightning Network. In the updated story, Alice is buying a laptop from an e-commerce store run by Bob.
