I'm a big torrent user, have been for so long now I'm actually still surprised that there hasn't been something better than torrenting or seeding to replace the way we download stuff.
But OK, if it's similar to Bittorrent token, why would I use it? Why switch over to something I have to have a Discord account for or a forum account for? Even for Bittorrent, you don't need to use their client to earn it, from what I'm reading.
The answer is rare files. Because seeders are incentivized to share by setting prices on their files, you can easily find files you want and if it's not available, post in a Discord or whatever Upfiring group you're in asking for it. Someone will provide it since there is a monetary incentive (in UFR). With BitTorrent, the original content provider provides the monetary incentive to keep their file alive, so this type of thing is not possible.
They're both good projects in their own right, I just think Upfiring has much more potential from where it is now to where it's going.
