Another option for sharing large files might be IPFS. Its a more n00b-friendly evolution of Bittorrent.
To seed a file, you can use a "pinning" service like Pinata, or run your own node, optionally over Tor like I do.
To share with others, you can give a normal http link to an IPFS gateway. They are damned ugly - https://ipfs.io/ipfs/bafybeicn7i3soqdgr7dwnrwytgq4zxy7a5jpkizrvhm5mv6bgjd32wm3q4 but they work like any other link if there are seeders online.
