I was thinking about this the other day. Isn't it possible to just rent/home host a VPS server and install IPFS on it (which I am considering) and upload your videos directly to your own VPS IPFS system to ensure your videos remain available - and not rely on IPFS as a whole. The other alternative I am considering is paying a yearly sub to Vimeo who will host your files as long as you remain in contract and pay the annual fee and then embed them in steemit.

I like the idea of decentralised storage through IPFS, but to rent a decent VPS server will cost about £20 - £30 a month equalling £240 a year at the cheapest. A 5GB weekly account limit on Vimeo is £60 a year. It is still cheaper to host through Vimeo than to rent a VPS to run IPFS.

Now you don't have to do either you can just rely on others and the current IPFS servers, but I feel that if you are a content creator here using Dtube, you really should be helping to support the network and improve it that is hosting your videos.
