In 2014, the IPFS protocol took advantage of the Bitcoin blockchain protocol and network infrastructure in order to store unalterable data, remove duplicated files across the network, and obtain address information for accessing storage nodes to search for files in the network.
Ah, thanks - you're half right :) The plan for Filecoin was initially (in 2014) to be based on Bitcoin, but since then this changed to its own Proof-of-Replication and Proof-of-Spacetime, reusing parts of Ethereum.
IPFS itself has never had any cryptocurrency integration, although there are external services that store your data on their IPFS nodes in exchange for Bitcoin.
