Storj is genuinely useful. It is however regular cloud storage, except the storage nodes that must be trusted will survive the company somehow. However the authenticated client-side encryption will protect your data, so the safety claim checks out, not sure about liveness.

Slapping a decentralized sticker on and having a cryptocurrency apparently worked out for them. This is how you successfully differentiate a product.

And what's amazing is that the coin has a market cap of $450m (probably still expensive if comped to someone like Dropbox).

If something with that utility is so lowly valued, then imagine the true intrinsic value of BTC!
