Both smell like a scam, "coincidentally" today storj started fundraising by getting people to send them bitcoins for useless storjcoins they created, the worst part is people falling for such a scam, then again there's a fool born every minute which is a business model a lot of companies rely on.
In this case and in storjcoin case the actors behind it all remain anonymous
I can understand why -- with all the scams out there -- that would be one reaction. But note that Filecoin makes important technical contributions on top of the Bitcoin protocol. You can read the paper here: http://filecoin.io/filecoin.pdf
FWIW, we aren't really anonymous. Neither in the storj case (you can find who they are in their website), nor in the Filecoin case. (hi!)
The Storj developers aren't anonymous at all...Their names and photographs are posted in their pitch deck, and they're active on reddit. The Storjcoins won't be useless either; they'll be the native cryptocurrency in their apps, and from what I understand they intend to add the ability to send data directly to an address in the future.
