IPFS is just distributed content discovery and download.
Someone advertises the content to the network, then people looking for the content can find it. Usually the people who find it advertise that they now have it to the network too.
It has nothing to do with cryptocurrency but is commonly used as a great way to embed "larger" content into blockchains and other immutable stores. It works well for this because 1. The CID contains a cryptographic hash of the expected content 2. You can change where/how you store the actual content without updating the URL.
