One of the ideas is that smaller payment amounts are viable on a blockchain - and there will be mining or transaction fees assessed but there will be fewer and smaller fees. Point-to-point transactability cuts out the ubiquitous payment middlemen and it gives the person making the transactions CONTROL of their transaction data. No longer will business pay credit companies to learn about you - they will have to pay YOU to learn about you.

Data is worth billions and trillions of dollars. And blockchain allows you to take control of it.
