A bitcoin is just a measurement of satoshi's. How the dollar can breakdown to a smaller unit of value, so can a bitcoin. Micro transactions are the future. There's ways to send a single satoshi. Satoshi's will be the new dollar. $50 can get you 800,000 satoshis. If a bitcoin is 1 million USD then 1 satoshi will be one dollar.
A possible scenario in the future can be you going to get a loaf of bread at the store. That loaf of bread might cost you anywhere from $10 - $40 in USD as compared to 1 or even a quarter of a satoshi. This scenario is very possible due to interest, inflation and devaluation of the US dollar. This can very well be part of the flippening. That's why it's very important to continue buying bitcoin and hodling. Even $10 to $20 is thousands of satoshis. Here is a break down of bitcoin into micro values of satoshis.
Its not hodling until you can cash them in for a large amounts of value. Its hodling until Bitcoin and Micro transactions become the standard of spending. Thats where the ultimate gains will come in.
