How are you different from Sia, Storj, Filecoin? Some should remember that there is competition in crypto for cloud storage not to mention centralized entities.
Not 100% sure about how other crypto cloud storages are implementing their solutions. But what I have understood about this X Cloud is that they are even separating individual file pieces into different hosts and the file pieces are encrypted as well. That really breaks the chance to spy on the host side VS storing the whole file on the host side. So at least the privacy is playing a significant role in this project.
