Money is one of the important concepts, This section talks about money from the perspective of microeconomics.when people exchange goods and services without using money, this is called barter. "I'll cook dinner if you'll do the dishes" is an example of barter. Imagine an economy in wich i can sell services as a consultant to banks, but what i want is to buy a new suit. the clothing store that sell suits does not have any use for my services as a banking consultant. i sell consulting services for money, and i buy a suit using money. money serves as a medium of exchange. the bank does not sell suits. how can barter work?
I think this is one of the biggest potential use cases for crypto, the barter economy. Once lightning, plasma, sharding, raiden and all of the other scaling solutions are implemented resource sharing like what Filecoin are trying to do will become allot more common place and I can see a future where I will trade some cpu power for maybe some extra file storage space.
