I’m not part of any team, but I think you have to be more precise in what you mean.
By default, IPFS only shares files among nodes that are interested in them. So if you add files to IPFS, they will still only be on your computer – unless somebody else specifically requests them.
Q: how can i ensure something remains online?
A: you can do this by keeping one or several ipfs nodes online pinning the content you’re interested in backing up, the more ipfs nodes pinning content, the better redundancy you get. Tools such as ipfs-persistence-consortium, pincoop, and ipfs-cluster on top of ipfs allow you to share the costs of bandwidth with other people or organizations. Then, protocols like Filecoin will allow you to just pay the network to do it for you (i.e. similar to how people pay “the cloud companies”, but here you’re paying the network itself). (Filecoin is not live yet)
IPFS itself does not have transaction cost, nor does it has any promise it provides for storage built-in.Maybe you refer to FileCoin which will be a service on-top of IPFS which will offer storage service. The price of which I’m not sure anyone exactly knows right now.
