I think the main problem most blockchains face in terms of gaining mass adoption is trust. Especially when it comes to storage of personal data - most of us here who know atleast the basics know that our data couldnt be more safe stored in a decentralised way such as Sia, however I know there is a lot of miseducation out there and people dont trust blockchain tech yet.

I looked into Sia a while back it looks like a solid project and should see steady growth. The only problem could be that physical storage is becoming so cheap now - but it is nice to have an extra back up on the could somewhere
