Filecoin is a crypto money that can completely change the storage system we have been used to until now, and will provide innovations in blockchain usage areas.
You can mine Filecoin with data storage devices you do not use.
You can exchange Filecoin for currencies such as dollar, euro, ETH and Bitcoin.
In short, Filecoin is a system that allows you to sell or buy storage space that you do not use.
